I am repowering a Rawson 30, and plan to install a Yanmar 3 cylinder, 40 hp, the 3JH4AE. Before I make the plunge, anyone have a comment on this motor?

We have a 2gm20f, and it is just adequate with our 8 tons, so the 3-cyl is a good call.  The most important thing is sizing your prop.  You need to be able to hit full cruising rpms (I think ~3200 for you) for the engine to be happy - and for your warranty to be valid!

Beyond that, I haven't met a Yanmar owner yet who didn't love it.  Just plain reliable.

I have twin 4JH4-CE SD40 in my charter boat. It may be because of shifting abuse by charterers but I am now into my 3rd cone clutch replacement in 2.5 years.Cry
