Momentum is a funny thing. When doing a major boat refit/rebuild like this, momentum counts for a whole lot. More often than not, each project reveals 10 more problems than you expected. Each time these problems come up, momentum takes a hit and motivation goes down hard. Recently I’ve found myself half finished with many of my projects by hitting roadblocks, and a little lost on where to spend my time on the boat. Whenever I find myself lost, I revert to taking things apart inside the cabin. It is relatively easy work, and I feel like I am getting things done. However, these are mostly cosmetic issues that won’t get the boat back in the water anytime soon.
So with the weather cooling down, I decided it is time to focus my efforts on the monolith that is the Yanmar 4JH2E – my diesel engine. Not just the engine, but the entire engine room needs work before we splash. The primary issue in there is the need to replace the stuffing box. I could probably refurbish it, but will most likely go with a PSS shaft seal as a replacement. If you go back to the posts when I hauled out, you would see the broken propeller shim that caused a lot of vibration of the shaft and engine. This caused the shaft seal to leak, which in turn sprayed water all over the engine room. Unfortunately, to replace the stuffing box the shaft must be removed. In order to do so, one of 3 things needs to happen: remove the rudder, remove the transmission, or remove the engine all-together.
My plan for the engine is to completely clean it off of old paint and rust, replace all hoses and clamps, replace the rusted and busted air intake, and […]
One of the things I knew about Windsong when I first saw her was that all of the seacocks needed to be replaced ASAP. They are very old-school style Groco seacocks and all have corroded to the point where they are inoperable. What does that mean? If a hose were to leak, I would not have had a way to shut off the thru-hull and the boat would probably sink unless the hose or seacock was plugged.
Seacocks are meant to be the #1 insurance on the boat against sinking, and I didn’t have that insurance for the entire time I owned the boat in the water. Since I started the bottom job I have been contemplating how the heck to get the seacocks and thru-hulls off the boat. They were so corroded that unscrewing the thru-hull from the seacock was impossible. I spent many months contemplating my approach and did as much research I could on the subject. Unfortunately there aren’t many articles written on how to get this job done on old, corroded equipment. There are plenty of articles on how to take apart modern seacocks, but non on how to tear apart old ones with no hope of reuse.
I did, however, find a few blogs and forum posts from people who just cut the thru-hulls up with a Dremel or some other tool to help remove them. But with my limited experience in doing things like this, I really needed a step by step instruction on how the heck to do that. After some creative thinking and experimentation, I finally figured out how to do it and here I will show my process.
Here are the seacocks in the head with hoses removed. One is the sink drain, another is for the head itself, the other […]
