2008 Week Thirteen in Review

An Update from the Maris Pearl
This week, Old Tacoma Marine Inc continued organizing the Maris
Pearl
’s storage container and tool room. We also replaced the bilge pumps and some plumbing, and started to install pipes for the oil cooler.

Atlas-Powered Crane Barges Still Survive

I got a call from a mechanic in Pago Pago, Samoa, who works on an Atlas-Imperial 668 that powers a crane barge. He’s been having some problems with water in the oil and found me through the internet. I told him that it could just be rainwater, since the engine sat outside unused for a while, but he should look in the crank pit as well. There’s also a chance of rainwater coming down the stack, so he’s going to check that out, too.

There are a few other Atlas-Imperial crane barges around that we know of, including ones in Honolulu, Bellingham, Virginia, and Amsterdam, as well as the one in Pago Pago. The ones in the Pacific Rim area are probably ones that were surplused from the Navy shipyards in Honolulu during the 1980s, since they had a bunch of them at that time.

I think that they’re really neat, though, especially since they’re such a different application of heavy-duty power than I’m used to. With boats, the engine will be at idle for an hour or two while pulling up anchor or untying, then the engineer will ramp them up to full as the boat gets under way. With a crane, though, the engine will suddenly race and all the pyrometers will jump up to 700 and the heat sinks will get really hot and the crane will make booming and whining sounds, then it will all stop just as suddenly. It’s a sort of surreal display of horsepower.

An update from Big Swan Drainage

The engineer at Big Swan Drainage in Illinois, called me again (last conversation here). He said that he pulled out the exhaust cage from the cylinder that was giving him trouble, cleaned it out, replaced the gaskets and the sealing ring, and put it back together and back into the engine. This fixed the leak, and the engine seems to be running fine now.

The real test will be when the next big rain sweeps through the Winchester area and the pumps run fast, which will put a heavy load on the engine. If it still doesn’t leak, then the problem may well be solved. A heavy load will also allow the engineer to get the temperature readings I asked about last time, so if there is a problem we can keep trouble-shooting it.

We need help to grow

OTM Inc applied for a business development grant from the National Association of the Self-Employed for the second year. We applied late in the granting cycle last year and didn’t receive it, but we’ll keep trying. We need this grant to help boost the company’s involvement in the museum field. We believe that OTM Inc can become an invaluable resource for museums around the world that have antique diesels in their collections. To become that resource, we need to do lots more research and publishing, create more public programs, and keep finding new old engines – plus whatever other cool things I dream up.

OTM Inc also needs to provide these services if we want to continue as a viable corporation. As I’ve said before, a lot of these old engines are ending up in museum collections and if we don’t have the expertise to work with the museums then we won’t be able to increase our customer base. Plus, it’s fun to work with museums, since they have a huge interest in creating public programs.

Old Tacoma Marine Inc Stickers!

OTM Inc just ordered a bunch of stickers from the Sticker Guy. Here’s the design:

Old Tacoma Marine Inc Sticker Design

We ordered a lot of them and we’re going to make them available to any of you who want them. Just send us your address and we’ll mail a bunch out to you. More on that later.

More scanning

We are still scanning engine manuals like crazy, so keep checking for your engine manual or email us an engine model to scan next.

2008 Week Twelve in Review

An Update on the Maris Pearl

This week I cleaned up and organized the Maris Pearl’s tools and spare parts:

“Spare

Jay recently bought a new storage container and had me lead the move from the old container to the new. Changing storage areas like this is a good time to inventory and organize the stuff you’re keeping with your boat and make sure that you’re holding onto the right things. Every time I do this for a client I find tons of parts that don’t fit the engine they are intended for. Since holding onto the wrong parts is a waste of space and effort, I try to arrange trades or sales of the wrong parts and get the right parts instead.

The Maris Pearl has a Q Enterprise, but many of its “spare parts” that Jay has been storing are for a G or R Enterprise. I’m working on trading them in to Striegel Supply for store credit, but if anyone reading needs parts for a G or R Enterprise, or has parts for a Q Enterprise, maybe we can arrange something.

Despite the clutter, Jay has some really neat spare parts, including a brand new cylinder head still in its original factory crate:

Classic Workboat Show 2008

On Saturday, OTM Inc met with representatives from the Northwest Seaport and the Center for Wooden Boats about holding another Classic Workboat Show. After some discussion, we decided that it was too soon to hold another show featuring tugboats, but holding a Classic Fishboat Show is doable for this fall.

The Classic Fishboat Show this fall will be great, but Old Tacoma Marine Inc won’t be as heavily involved. The 2009 Classic Workboat Show, though, will be epic, with even more heavy-duties, more events, and hopefully a big crane barge demonstration. We’re already looking for sponsors and donors, so give us an email if you’re interested or know someone who’s interested.

For those of you who missed the party, the first-ever Classic Workboat Show was last October. It was by far the best boat show I’ve ever been to – and I’ve been to a lot of boat shows. I may be biased, though, as OTM Inc was a major sponsor of the show and I helped put a lot of it together with Northwest Seaport and the Center for Wooden Boats. The best thing about the show was getting together six of the eight remaining boats powered by Washington Iron Works Diesel Engines all lined up at the Historic Ships Wharf at Lake Union Park. The restored tugboat Donald R, the research boat turned charter boat Catalyst, the monkey boat David B, the tugboat Ruby XIV, and the hard-working Western Towboat tug Fearless (formerly the Ruby II and the Discovery) joined the museum tugboat Arthur Foss for one awesome lineup of Washington power:

We also had the tugs Lorna Foss and Newt on “Atlas Row,” and the Joe, Teal, Propeller, and a couple other boats in the non-heavy-duty section (but we thought they were great anyway). A Sea Scout troop did a scuttlebutt demonstration on the wharf and we held line-toss and bollard-lasso competitions for all ages:

To complete the festive atmosphere, Ballard Brothers Seafood & Burgers set up a booth selling their famous blackened salmon burgers and the jazz trio Bar Tabac played old-timey music on the docks and the boats. We even set up a pub, sponsored by Pacific Maritime Brewery.

The best moment was at five o’clock, closing time for the show. All the workboats sounded their horns, whistles, sirens, and bells at once. It was totally unplanned except for me telling everyone to blow their noisemakers at five, and it became this amazing workboat symphony. I can’t even describe how awesome it is, you’ll just have to listen to it yourself. It was an amazing day and I think it will be tough to beat. The fishboat show this fall will be great, but I think that the 2009 Classic Workboat Show will be even better. I hope to see everyone there.

If anyone reading can help with the 2009 Classic Workboat Show, we need sponsors, visiting workboats, volunteers, and cash (and see if your employer has a program for matching funds, since it’s a great opportunity for sponsors to get their names out there). Donations can be earmarked for the show or for other programs. Email me or Northwest Seaport to help.

A Unique Two-Cycle Atlas-Imperial

Finally, this week Chris from Utah sent pictures of the only two-cycle single-cylinder Atlas-Imperial diesel engine I have ever heard of. If anyone reading this knows of another, please let me know.

We borrowed the two-cycle Atlas-Imperial manual from Dan and scanned it for you to read. I read through it as well, and it seems like Atlas stole the idea straight from Fairbanks-Morse.

What do you think? Read it and let us know on the Discussion Board.

More Scans Coming Soon

Speaking of scanning original diesel manuals, Old Tacoma Marine Inc scanned a whole bunch of original heavy-duty manuals and catalogs this week to post on the website as a resource to enthusiasts, operators, and history geeks. We’re still getting them formatted for the web, so stay tuned.

Meanwhile, what manuals do you want to see scanned and posted on the web? Make a request and we’ll track it down and get it up–as long it isn’t about lawnmower or washing machine engines. Heavy-duties only.

Tours for Guy

Guy [formerly] from Kodiak, who sent us the great photographs and information about the Kodiak Maritime Museum’s Washington Iron Works engine, visited Seattle on Saturday and called to ask if he could see some old engines. We were happy to help – we sent him to the Northwest Marine Propulsion Museum to see their Washington and to Northwest Seaport to see the Arthur Foss’s Washington. It’s too bad that he didn’t get to see them run, but he’ll just have to visit again during a demonstration.

Get Your Heavy-Duty Fix

Hey all you Seattle engine and tugboat people! Here’s a chance to get involved with some old iron this spring: Northwest Seaport, which owns the Washington-powered Arthur Foss, is currently recruiting volunteer docents to lead tours of the tug and its engine room:

Six-cylinder Washington Iron Works diesel engine in the historic tugboat Arthur Foss

They don’t seem to have the information up on their own website yet, but I’m told that this Spring’s training session starts on March 29 and that they’ll be providing lunch for the volunteers who take the course and commit to being docents this year. It sounds like a sweet deal for you out there in Seattle to get to know the largest remaining Washington diesel (18″ x 24″, six cylinder), although I think you have to talk about other things as well.

Call Northwest Seaport at (206) 447-9800 to sign up, or send an email to volunteer@nwseaport.org, and tell them you heard about it from Old Tacoma Marine Inc.

2008 Week Eleven in Review

An update from the Maris Pearl

This week we pushed to get the Maris Pearl running again to move it back to Shilshole Marina. Once it was good to go, we took the time to change the oil in the main engine: all 250 gallons of it. We also changed out the oil filters and watched two painters begin work (they also helped take the boat back through the locks). It was another uneventful trip.

An update from the David B

We got call from Jeffrey on the David B, following their shipyard work. They replaced the stern bearing and had some pitch taken out of the prop, bringing the RPM up to 288 with pyrometers at 625 degrees with a speed of 7.9 knots (a 1 knot increase). I still want to see 325 at 600 degrees, but its better than it was. Good work, David B crew!

An update from the Velero IV

Irv from the Velero IV visited the shop the other day. He wanted my opinion on how he’s going to replace the steering mechanism. Currently, it has a worm drive and bull gear, but he wants to use hydraulic rams since they’re more reliable. I think that sounds great and I’m looking forward to hearing about the replacement process.

An update from Waimea

Research on the Sugar Mill Camp Museum’s Washington Iron Works engine in Waimea, Hawaii is progressing slowly but surely. Dan let us borrow the photographs that his wife Carol took when she visited in 1998 or so:

Washington-Estep diesel engine at the Waimea Sugar Mill Camp Museum in Hawaii

In addition to being great photographs of an old Washington Iron Works diesel engine (an Estep, even!), this gave us the serial number (it looks like 7182 but is really 7162). The serial number let us look up the original Washington Iron Works manufacturer card, which showed that it was purchased by the Kauai Fruit & Land Company in 1928 through the Perine Machinery Company of Seattle, then sold to the Waimea Garage & Electric Company in 1932. The company later bought two other Washington diesels (numbers 7410 and 7587; they must have liked them a lot.

This finally gave us an excuse to email Chris in Waimea again. She works at the Kauai Museum by day and with the fledgling Sugar Mill Camp Museum when she can. She told us that the engine had been sold by the Electric Company when they upgraded their equipment. We haven’t nailed down a date for this; they bought their last Washington diesel in 1945, so maybe this one replaced number 7162, or maybe they upgraded in the 1960s or 1970s to high speeds and got rid of all three Washingtons at once. I don’t know, but we’ll try to find out.

Anyway, Chris said that after the Electric Company sold number 7162, it went to the Kekaha Sugar Mill and powered the pumps used in the sugarcane irrigation ditches. It turns out that Kauai’s sugar cane industry relied on these irrigation ditches, which makes me wonder if Hawaii is full of old heavy-duties rusting away in the fields. Anyway, her cousin Mike rescued this engine after the Kekaha mill went under, and brought it to the Sugar Mill Camp Museum, which is located on the former Waimea Sugar Mill site. Chris says that she’ll send us a CD of photos, and it sounds like Mike might be interested in doing a little ground research for us.

This is especially exciting news for two reasons. First, the serial number confirms that this engine is the second-oldest remaining Washington Iron Works diesel engine (the oldest being the Kodiak Maritime Historical Society engine that Guy alerted us to). Second, from the pictures, it seems to be unusually complete. I don’t see anything missing, which is uncommon considering how engineers can behave like scavengers when it comes to old engines.

Stay tuned for future updates. This is a neat story that’s unfolding.

Atlas-Imperial 668 pistons available

John in Oakland, who works on the Lightship WLV-605 Relief, called with a neat discovery. He said that volunteers with the United States Lighthouse Society, which owns the vessel, are moving some of the spare parts around and found that they have more pistons than they will ever need. They’d like to sell some of the extras to free up storage space and maybe make a little cash for buying other needed parts. If anyone reading this has an Atlas-Imperial 668 and would like some spare pistons, comment here so we can forward the request, or just contact John on the Oakland lightship at (510) 272-0544.

Read the manual!

One of my on-again off-again customer is calling me regularly for free engine trouble advice. While I don’t mind talking shop, anyone working on the heavy-duties should read the engine’s manual over and over again so that you understand how it’s supposed to work. Also, keep the engine clean – really clean – so that leaks can be found and fixed quickly. Good gages and monitoring equipment are also worth the price to install them, since they let you know what’s going on inside (though remember that gauges are not always accurate).

Sometimes, an owner will want to throw money at the engine blind-folded. If they ask me to get involved, I will ask for gauge readings and symptoms before I do any work on the engine. Throwing money blindly into the engine isn’t criminal, but I want to see measurable results and this usually requires patience.

Living the tugboat dream

As I mentioned previously, OTM Inc is getting a lot of calls from people interested in old tugboats for sale in Seattle. I feel like I’m acting as a broker for boats powered by heavy-duty diesels, but I don’t mind because I like seeing these old boats go to good homes.

What I do mind is how many people don’t really realize what they’re getting into by buying an old tug to live on, fix up, and cruise around Puget Sound in. Boats are expensive. They require a lot of maintenance that is in addition to the repairs and overhauls and other fixes. Even boats in great condition need a lot of work. One of the best examples of this is the tugboat Newt. She is a beautiful home for Eric, Laura, and their two kids and is in great shape to the rest of us, all clean and cared for with lots of bright wood and a great Atlas-Imperial diesel. When Eric (who is a very talented guy) gets talking about the boat, though, he says that he feels that about half the work is “done.” I like hearing that, because it shows that he and Laura are responsible tugboat live-aboards who realize that an old boat will always need work.

Back to Old Tacoma Brokerage. I’ve been talking with two “clients” who worry me a little bit because I don’t think they realize what they’re getting into. First, a guy and his wife called me about buying an old tug to live aboard and be their ticket to joining the tugboat enthusiast club. We showed them the Briana Marin, a great tugboat powered by an Enterprise DMG-6 engine (and took pictures of the engine room while we were there):

Enterprise DMG-6 diesel engine in the tugboat Briana Marin

It’s about 65 feet long, very comfortable inside, and easy to maneuver with both a reverse gear (installed after a previous owner had some problems learning about direct-reverse) and a bow thruster. It was built as a tugboat-yacht, later used hard by a San Francisco lightering company, and then used as a yacht again by a doctor, then a scoundrel, then a local tugboat guy. A few years ago, the main coupling crapped out and the current owner put it up for sale rather than pay the very hefty repair sum.

During the tour and in later phone calls, I tried to scare impart to him the responsibilities of tugboat ownership, as I do all potential buyers. I described all the work that I think needs to be done on the Briana Marin, including replacing the main coupling which is priced at $25,000 plus installation fees. I was trying show that old boats need constant maintenance and repairs, and to get him to think long and hard about the responsibilities of boat ownership.

Apparently, he got the wrong message; he called on Friday asking what I think of a 108-foot steel tug with a Fairbanks-Morse opposed piston diesel. Holy crap, that’s almost twice as much boat as the Briana Marin! He reported that it’s in perfect condition, but I say that even a boat in perfect condition is a lot of work to maintain, since it still needs yearly dry-docking, painting, engine tune-ups, moorage, registration fees… I recommended that he buy a smaller boat and practice before moving up to that 108 foot tug. The Briana Marin, despite the work needed, would be a good tug to learn from, since she’s so maneuverable and not too big for two people to handle. Plus, she’s a pretty little boat:

Tugboat Briana Marin at the Ballard Mill Marina

Second, an upstate New York couple just moved to Seattle and are looking to buy an old boat to move into, fix up, and eventually cruise in. I call this plan “Living the Tugboat Dream.” They got my number from John Callahan in Kingston, New York, who’s the lead guy on the tugboat Chancellor. I like John a lot; he’s the organizer of the Waterford Tugboat Roundup in Waterford that is one of the best parties I’ve ever been to. Anyway, these two used to live in Kingston and hang out with the tugboat guys there, and mentioned to John that they were moving to Seattle and looking to buy a tug. Naturally, John passed on my number.

I met them at Hattie’s Hat in Ballard, then we went down to the Briana Marin as well. They liked the boat, but they’d already toured the J S Polhemus that’s currently at Ewing Street Mooring. The Polhemus is a neat old work tug that I don’t know much about except that it’s also got a nice Enterprise DMG-6 and is for sale by owner (an artist guy who decided that he didn’t want to be a tugboat guy). I don’t think that it’s a good choice for a first tugboat, though, since it needs a lot of work (unlike the Briana Marin, which other than the coupling doesn’t need very much right now work).

I gave these two the the same spiel that I’d given the earlier guy and his wife: boats need a lot of time and money to keep afloat, regardless of the purchase price. They said they knew, but that they are determined to make it work. This frankly worries me, since good intentions without money to back them up have sunk more than a few old boats. See, they’re sort of thirty-something Bohemian types from how they present themselves. She’s a leatherworker, he works with computers. I’m really afraid that they’re looking to buy and old tug and live aboard because they think it’s cheaper than buying a house in Seattle. While it is getting expensive to buy a house, it’s just as expensive to buy a boat. Rather than a mortgage, you’re paying moorage and dry-dock costs and mechanic fees – not to mention paint and oil and fuel, plus major restoration projects like repairing damage.

I know that I’m starting to sound like a broken record and like I’m trying to poop on the party, but people just don’t realize how much work it takes to keep a boat going until it’s gone and they’re deciding between hiring a salvage company so that they can claim the insurance payout, or just walking away.

Another problem I see is that boats don’t act like houses, and most people know more about houses than boats. If you leave a house alone for a few years while you’re living in it and saving the money for a remodel, chances are it’ll be fine. If you leave a boat alone for a few years while you’re living in it and saving the money to dry-dock it and repair the slow leak in the forward bilge compartment, chances are it’ll sink dockside. This illustrates what I call the “Work/Money Curve.” If you don’t keep up with maintenance and repairs and make progress, then the boat starts to fall behind and you need more and more work and money to bring it back. If the boat falls far enough behind, no amount of work or money will fix it and it’ll slip off the surface of the earth – or rather under the surface of the water – without anyone noticing:

An abandoned tugboat on the edge of Barnard Harbour.

I don’t know. Maybe I’m being harsh and these folks really do have the means and the drive to make it work. I have seen some success stories, like the Newt and other tugs that their owners keep looking great through hard work rather than huge bank accounts. I’ve just seen a lot more that end up getting behind that curve and getting ruined. Does anyone reading have an old tugboat success story that they can share? Comment here, or better yet, post to the Tugboat Dream thread at Old Tacoma Marine Inc’s discussion board.

Anyway. I haven’t heard from anyone about either the Briana Marin or the Polhemus for a few days. I was hoping that they’d call me back so that I could show them some other tugs in the area, but they haven’t yet. The ball’s in their court.

2008 Week Ten in Review

Maris Pearl Update

This week, Old Tacoma Marine Inc finally installed the Maris Pearl’s jacket-water cooler. It wasn’t quite as smooth a process as I’d liked; after I put it in the first time, I had to pull it out and turn it around. Some of the pipe runs that I welded will need to be modified later, but it is in place and holding the jacket-water just fine.

This job is just about over, but it looks like the owner has plenty more for me to do on the Pearl before taking the boat up to Ketchikan in a few weeks.

Big Swan Drainage Problems

We got a call this week from the Big Swan Drainage & Levee District in Winchester, Illinois about their 400 horsepower Atlas-Imperial diesel. This engine is still coupled to a pump and used to move rain water from a ditch over the levee and into the river. This is one of my favorite engines because it’s still doing exactly what the district bought it to do more than fifty years ago, and they’re invested in keeping it running.

The Big Swan Drainage’s engineer called because he thinks that one of the cylinders isn’t firing, as it’s running cold, making hissing noises, and the exhaust valve cage is smoking a little. He asked me about what it would take to install a new cylinder. I said “Whoa, wait a minute!” Replacing an entire cylinder is the very last step for a problem like this – it’s a little like saying that because you have a cough and a fever you need a lung transplant. There are so many different little problems that could lead to an engine making weird noises, smoke, and giving low temperature readings that it’s best to work through symptom by symptom to fix problems and rule out causes.

The very first step is to double- and triple-check all the readings, using the built-in pyrometer and a hand-held infrared meter to determine the actual exhaust temperature. It can also be really useful to just put your hand on the exhaust manifold elbows, too. Using these different sources of information about the exhaust temperature is important to nail down exactly what the cylinder is doing.

I know of one guy who noticed a really cold temperature on the number six cylinder’s pyrometer during a routine check, so he boosted the amount of fuel going into the cylinder. It takes a while for any adjustments to make a significant change in engine temperature, so he went back up to the bridge until it was time for the next check. When he got to the engine room, number six cylinder was belching out smoke. He limped in to port and called a mechanic to come take a look at it as soon as he could. The mechanic found that the cylinder head was cracked – the increased fuel had increased the heat in the cylinder and expanded the casting enough to crack. While messing around with the cylinder head, figuring out how to fix it (it is not easy), the mechanic found the pyrometer wire laying slack behind the engine, unattached to the cylinder. The low temperature reading that led to the fuel adjustment was because the pyrometer wasn’t hooked up.

If the exhaust temperature on the Big Swan engine really is too low, then there’s still several more things to rule out before replacing a cylinder. I’ve found that it’s not very common for a cylinder to suddenly not get enough air or compression and fire incorrectly, but it’s very common for it to suddenly not get enough fuel. The next step is to check the fuel system, starting with the adjusting nut at the top of the fuel injector. This should be moved in very small increments, with the original position marked with a paint pen. If there’s still a problem, then I’d service or replace the injector. Once I was really sure that the cylinder was getting fuel and air, I might consider compression issues.

Since the Big Swan engineer also mentioned a leaky valve cage (which could be caused by a wrinkled copper gasket; easy to replace), I think that systematic testing like this will identify the problem before he gets to the “replace the cylinder” step. I hope it’s an easy fix; it’s a neat engine and I want it to keep running with minimum fuss for a long time.

Starting problems with the Oswell Foss

Later in the week, Captain Jim called us from the retired tugboat Oswell Foss about start valve problems on its G-series Enterprise diesel engine. I’m planning a trip to the San Juan Islands in a few weeks anyway, so I’ll look at the controls and air starts then. The symptoms he listed include air bleeding down fairly quickly if the handle is not in just the right spot, when earlier the handle had a little more forgiveness.

Field trip at the Northwest Marine Propulsion Museum

I finished off the week with coffee at the Northwest Marine Propulsion Museum next to Ewing Street Mooring. I thought Dan, Mike, and I would just talk shop, but it turned into an event. About eight members of the Puget Sounders chapter of the Antique Outboard Motor Club Inc showed up to take a look at old engines. Harold from the club told stories of working for Washington Iron Works for many years, which was quite a treat. We also ran the museum’s three-cylinder Atlas-Imperial diesel and talked shop for about an hour. It was a nice way to relax a little before heading back to the Pearl.

2008 Week Nine in Review

An Update from the Sobre las Olas

This week started with a great call from the guys from the Sobre las Olas. Owners Sean and Jeff and engineer John were all very excited to tell me about how they ran the engines for the first time without my help. I am very excited to hear about this boat coming back to life. It’s a long way from where it was about four years ago. Sean and Jeff have put a lot of work into the boat – and twice as much worry.

Atlas-Imperial

I had met Sean and Jeff a few times while working with Dan, and heard about the repair estimates for the engine overhaul, but I first talked with Sean about four years ago when a rumor swept the very tight old engine community about how the owners were considering replacing the original Atlas-Imperial engines. Apparently, the sticker shock of Dan’s proposed $300,000 overhaul made Caterpillars look really good.

When I heard that, I called Sean immediately. He was blown over by my rant on the importance of preserving treasures like the Sobre intact, since just a few days earlier he’d talked with the San Diego Maritime Museum about donating the engines. He couldn’t believe how important it was to the old engine guys that the engines stay with the boat, and was amazed by how they all immediately got on the Red Phone and to sound the alarm. I had a feeling that I was not the first to talk him out of pulling out the Atlas-Imperials.

I also wrote a very convincing email to Sean on how to own two heavy-duties with less fear. The conversation, the clamor, or the email must have worked, as I have been flying down to Los Angeles regularly to repair and maintain the Sobre’s engines ever since.

The Sobre is a huge project that has the potential to go completely out of control at any moment, but the guys are doing a great job in my opinion. They take a few big steps then rein it all in and take small steps for a while, but they never let the health of the boat go backwards. That’s the way to do it: slow and steady, just like these old heavy-duties. I hope to see Sean and Jeff cruising soon in their treasure of a classic yacht.

Another update from John in Maryland

Early this week I had another conversation with John in Maryland. He is really excited that other people care about these old engines. He also wanted to brief me on the condition of a light ship he is volunteering on and how maintenance is often neglected. It’s a common story in the non-profit and museum world of historic ships – many people don’t realize that these boats were decommissioned or retired when they ceased being cost-effective to maintain. Museums and non-profits need to realize that if the government or a business can’t afford the ship any more, then they may have an even harder time maintaining it. Keeping an old ship as a museum vessel is possible, but you have to know what you’re getting into and have a plan for how to keep it going beyond “but people love her!”

And back to the Maris Pearl

On board the Maris Pearl, we removed the old heat exchanger and lowered in the re-tubed heat exchanger. I also cleaned the bilge really well and painted the port side bilge with two coats of epoxy paint. The end is almost in sight.

Old Tacoma Brokerage?

We also had a visitor looking for an old tug powered a heavy-duty to use as a live-aboard. This is the third call I have had for a tug in the last two months. I think OTM might want an classified advertising portion of the website, but until then, all you tug boat owners who are looking to pass the boat on can email me at adrian@oldtacomamarine.com. I will try to play match-maker.

OTM Inc also had to do taxes this week… Totally lame.

An update on the Catalyst

The Catalyst won’t be overhauling a cylinder this year after all; they’ll just change the leaking grommets under number three head, inspect the bearings, and adjust the propeller’s pitch so that they can run the engine up to normal operating speed.

Lugging is a common problem with the heavy-duties, caused by over-pitched propellers or too many parasitic loads. Engines with caged valves don’t dissipate heat very well, so we recommend not exceeding exhaust temperatures of 600 degrees. All the cylinders should have this exhaust temperature at the highest comfortable running speed, not exceeding the rated speed.

This all sounds vague and technical, but an engine might be rated for 450 RPM and so the fuel and load (propeller size and pitch) should be set to achieve 600 degrees at 450 RPM. However, if at 450 the engine starts vibrating uncomfortably, then back it down until it’s comfortable again – maybe at 442rpm – then use that RPM for all your calculations. Okay, so no one is going to take the propeller off every trip until its right; I’m just recommending that owners get familiar with their engines and try to adjust them, rather than just running them up to the number written on the side.

And remember the pitch of your wheel has nothing to do with your manliness.

An update on the David B

The David B is going with the machined plastic bearing without removing the shaft. I hope it works! Don’t forget to align the engine afterwards.

A new owner for the J S Polhemus?

Kate emailed for more information about the J S Polhemus and its Enterprise diesel. She got our number from John Callahan in Waterford, New York – a great tugboat guy. I’ll be showing Kate around the Polhemus sometime next week. It’s currently in Ballard at the Ewing Street Moorings.

Castings from Keith

Finally, OTM Inc got an email from Keith Sternburg with pictures of his amazing castings for a steam engine:

It may not be a diesel, but those look great, Keith.
