2010 Week 24 in Review

This week, OTM Inc got back aboard the Maris Pearl to get ready for some serious engine work. We organized the tools on board and cleared out a space in the shop, then we worked late one night to move the two spare cylinder heads into the shop and pull them out of the crates.

We also brought all the spare valves and jewelry from storage to assemble the heads. The new valves and new seats looked great! We did do a bit of lapping so we could easily see where they meet.

Thanks to Ed Ehler at EMS Marine for use of the forklift – we would have had a terrible time loading the heads with out it.

Then, we bought three head gasket kits from Brunner enterprises. They have a lot of Enterprise parts on the shelf, but be sure to look up the part numbers before you call. At the end of the week, we moved the boat to Ballard Oil, took on fuel, stripped down the number one head, and pulled apart the oil filter

Lightship Request for Proposals

This week we also finished up some details on the draft Lightship No. 83 Request for Proposals for Phase One Construction Activities, and sent it off to the state DOT for a final look-over before we go to press.

Washington injectors, finished!

This week, OTM Inc finally finished rebuilding the injectors for the Timber Heritage Association‘s Estep yarder. Two of the three operate well, but the third has a smashed tip that I hope they’ll order replaced soon. In the meantime, all three injectors look great!

Enterprise injectors, begun

Martin from Hatch & Kirk is working on a new injector nozzle for a G Enterprise, so we dug up one of our spare heads to check the spray angle and tip depth into the cylinder.

Martin and I also disassembled four injectors from the Maris Pearl, then inspected, reassembled, and tested each. It turns out that even though they were leaking, three of them were within specs. The fourth was ruined and it’s a good thing we changed it out: the pintle had been badly scored, possibly from dirt. We’ll discard the worn parts and save the rest for spares.

Lightship 83 Request for Proposals

In the office, we’ve made a bunch of revisions to the draft Request for Proposals for the Lightship project. Hopefully, it will go out on the street soon.

Work on the Arthur Foss

OTM Inc is assisting Ocean Bay Marine in buttoning up the Arthur Foss. We’ve decided to pull the tarp and seal up the wheel house as best we can with the funding available. This will bring the work on the wheel house to a good stopping point, but not a finishing point. We hope to tackle it again next summer with renewed funding dedicated to the project.

Work on the Maris Pearl

Meanwhile, back on the Pearl, we’re looking for water leaks in the engine, as it seems a few cylinders are leaking water into the base – not enough to turn the oil milky or anything, but still a few drips when it’s cold (none when it’s warm). It looks like we will be changing out some cylinder heads soon.

California Planning

In future news, OTM Inc is planning a trip south to see the Portola and the Sobre las Olas. We got a request to perform an engine survey for the Portola, in addition to doing a few repairs and acting as engineer for a few trips. A potential buyer who obviously has really good taste fell in love with the boat and wants some technical advice and assistance. I’m looking forward to seeing her out cruising again, so I hope the sale works out.

While in California, I’ll do some more work on the Sobre, another beautiful heavy-duty yacht. This ought to be a fun trip. Details soon.

OTM Inc, the educators

For years, we at OTM Inc have been using heavy-duty diesels as training aids to people new to diesels. Our collaborative high school classes have won high praise, and now we’re working with The Anchor Program to design more educational opportunities for those interested in engines and boats. More on this later.

2010 Week 21 In Review

This week, OTM Inc finished changing out the injectors on the Maris Pearl and bled all the air out with a big pry bar under the injection pump. With the fuel rack at full, I manually pumped a bunch of fuel through the lines. Then we very cautiously took it out on a short trip around the bay. It fired on all eight cylinders without even a hiccup.

More work on Washington injectors

We’re also working this weeko n fitting all the parts on the Timber Heritage Association‘s Washington injectors.

Boats and Parts for Sale

The J.S Polhemus is for sale again, if anyone’s interested in a worthy project. It runs and floats – what more do you want?

If it’s extra engine parts you need, that’s okay – theCaptain Reino‘s DMG8 is being parted out. Contact us for more info if you’re interested.

OTM Inc started this week cleaning up after M4. What a great show.

More fitting parts

We’re also still working on fitting parts on the Timber Heritage Association fuel injectors. I actually got an email from the machinist we use to have Washington tips made. He said:

“I’ve been working on the numbers pretty hard, I didn’t think you’d like a $300 price for tips. Our biggest hurdle has been fixturing, keeping the concentricity of the sac within .0015″ at that depth isn’t easy. The best I can do is $150.00 each in 12 pc lots with six drilled & six not, 6 drilled comes in at $214. If you have the fixture to hold these while drilling the spray holes (that we can use) knock off $50.00 each.”

Seattle Tug Boat Races

This year’s Seattle Tugboat Races were this Saturday, and although the race results were anticlimactic for the heavy duties, the Maris Pearl won the Tugboat Annie Award. Yay! The Chief finished the race under its own power. Another yay!

Finished on the Maris Pearl

This week, we finished painting the Maris Pearl‘s Enterprise diesel engine and cleaned up so the owner and his family can get under way. It feels good to have the job done.

The Timber Heritage Association sent three more injectors to the shop and so just like the last set, we tore them down and cleaned all the parts made a list of missing or broken parts and started fitting all the parts for interchangeability.

Tug Boat Party

The International Retired Tugboat Association had a very nice gathering this week on Tracy and Giles’ tug the Olmsted in Ballard. It’s a great party where representatives of several old tug boats shared stories and advice.

I’ve been going to the party for years and can’t help but notice the association evolving to more of a family-friendly support group from the can-crushing machoism I remember. I don’t know if it’s the slowed economy or the aging boats we like or the dozens of other maritime pressures affecting the old tugboat community. I admit I am only loosely connected to the IRTA, but I remember more chest-thumping pulling contests and heated arguments about race statistics.

Even without the machoism, though, the IRTA is a wonderful group and I know that old tugboat owners love company.
