Earlier, I shared how we had finally sealed the cockpit sole/engine room. Well that was so last Saturday. The real action occurred on Sunday when Shawn Thur, our Diesel Mechanic, came down to finish the alignment of the engine and start the repair on the cuts that were made to remove the cutless bearing.
Since the work to repair the keel would require some time to allow the resin to cure, Shawn got right to work prepping the area.
Using a Skilsaw and and a sander, Shawn roughed up the surface of the existing fiberglass with a Skilsaw. Another lesson learned. This looks like a superior preparation for laying on new material.
to pack in around the new nipple that houses the cutless bearing, Shawn uses a product called Kitty Hair. This is a polyester resin with long strand fiberglass mixed in. While not an epoxy resin, it is waterproof and considerably easier to use than plain resin and woven glass.
From what I have read so far, this product is essentially the same as what was used in during the manufacture of the boat but in a very convenient and easy to use package. Add a little cream hardener,mix and you you are ready to repair just about anything.
While the initial layers of this repair were hardening, Shawn and I went below to begin the final alignment of the engine.
The main issue with finalizing the alignment was that the ass-end of the engine needed to drop another quarter inch. To accomplish this, Shawn picked up nuts that were only half as thick as the nuts that came with the stock engine mounts. Even with these nuts, we ran down pretty close to the bottom of the feet. That is not a bad thing as it lowers the center of gravity of the engine and applies less torque to the engine mount studs.
Once Shawn had replaced the leveling nuts, he could then finish aligning the engine coupling to the shaft coupling. I don’t have any photos of that alignment as Shawn was hogging all the space. But he was making noises that sounded positive. Using a dial micrometer with a magnetic base, he had me slowly turn the shaft to check the alignment. By the time he was done, the shaft was within 1/1000 of an inch. With that kind of tolerance, finishing up the coupling was pretty easy. This coming weekend, I want to at least lay hands on these nuts and bolts to make sure I am clear on how they are adjusted. I think a lick of paint on some of these parts wouldn’t go amiss. The feet are not stainless and the engine coupling was already showing rust spots even though it looked like stainless.
I think Shawn was ready to fire up the engine after all of this work was done but I have only roughed in the electrical and fuel systems to the engine. That will be priorities one and two when I get to Astoria this week end. I also have new parts for the exhaust system which I hope will allow me to finish that project.
Shawn is proposing that we pull the impeller from the raw water pump and run the engine for a few minutes with just the fresh water recirculating for a few minutes. On the hard, I have no readily available freshwater which I could use to run the raw water pump. The yard is persnickety about folks using water on their boats lest we start flushing copper paint into the Columbia River. I was thinking that I could dump 30 or so gallons into the bilge and use that for my raw water supply. Thoughts, anyone?
Finally, I’ll leave you with this beautiful photo of the new prop. This was hung on the new shaft to facilitate the alignment.
I have the old prop which I plan to have cleaned, balanced and saved as a spare. It may not be as structurally able as this baby, but it will be a nice backup.
