All of hoses in the cooling system on my Westerbeke 10 Two appeared to be original from 1985. One hose had already blown with the previous owner, so I decided this should be a project to tackle early on. This project ended up spanning many months as new "opportunities" arose. So, let's jump in.
Here's the 'before' pictures:
First, I bought a radiator hose from O'Reilly so I could use the engine.
That got me through until I was ready for my summer haul-out. I ordered a full set of hoses from Westerbeke (for "special" hoses) and ordered generic marine-grade hose for the others. Those all installed without any incidents. I documented my heat exchanger refurbish my exhaust flange woes in detail on other threads, so I won't re-hash them here. But the fun continued when I started to try and remove the mixing elbow for re-use. After using a pipe wrench to separate the nipple and what was left of the flange, I decided I wanted to use my new nipple, too. So, I took the wrench to it...
GAH! Yeah, it deformed. Well, no turning back now; I'm committed to removing it. After applying lots of heat, using a 3-foot pipe wrench (with an extra extension pipe for leverage), it released. There was a small crack created in the mixing elbow as a result (which I sealed with JB Weld). I decided to add a couple of SS elbows to elevate the mixing elbow a bit and add some exhaust heat wrap (there was none before). The hose going to the muffler provides some support, so the weight shouldn't be fully on the flange. Here's the end result.
Upon firing up the engine after a re-splash, I noticed the water pump belt was "jumping" all over the place. Long story short, I replaced a mangled impeller only to find the whole water pump was really not rotating well; probably worn out bearings. Looking at rebuild versus replace, the cost difference was about $90. Well worth my time. So, I bought a new raw water pump. Pretty easy to install and it worked really well - pumping LOTS of water, now.
Here's the end result of the whole project.
Of course, this has spawned a couple of new engine items I'd like to take on; new engine belts and replacing the shabby siphon break. The fun never stops.
