Repowered my Bristol 30 with a Beta. Not only less expensive but as it is based on a Kubota diesel parts are everywhere and less expensive.
It's design incorporate's maintenance ease...built in oil pumpainting etc. And great customer service.

And I have started looking for a new motor. First the problem. The engine recently started to leak a fair amount of oil and to start poorly. We spent a lot of time trying to find exactly where the leak was from and I had thought it was the head gasket. The local mechanic, Charles at Gartside, said he really didn't think it would be the head gasket as he had never seen an oil leak from one. We cleaned the engine with brake cleaner, got some florescent tracing dye, put it in the engine and let it run for an extended period. Although we some some oil leak never saw the florescence with a black light. Regardless we decided it must be coming from the intake manifold. Of course the leak is where it is almost impossible to get to but where the leak occurs there aren't too many options. The intake manifold can get too much oil in it if there is blowback increasing air pressure in the valve and rocker arm cover. So, while the engine was running I pulled off the breather hose which runs from the cover to the manifold. And there was pressure and there was oil which blew all over. Now for the first question. Everything I read says this is a result of a worn engine - rings, cylinder walls, etc. which leaks air into the crankcase building up pressure. Has anyone ever seen a different reason for this? I had a compression test done about 8 months ago and all was fine then. But that was then. My take is a 37 year old raw water cooled engine is not worth that kind of repair, albeit it only has 2,000 hours on it. Second question. I'm currently looking at a Yanmar and a Beta engine. Any comments? The Beta is cheaper. Also they sell a 25 HP which seems about right for the boat. Both appear too wide to get in on my C&C 34. Anyone have experience with this?
