Rebuilding a Yanmar YSM-12 using YSB head
We blew the Yanmar YSM-12 engine in our sailboat last summer and are needing to decide if we rebuild or replace. It needs a new cylinder head, Piston, rings and sleeve as well as crank bearing at the lease. The head looks like it would be the tough part but I have found a YSB-12 that is being sold for parts. Would the head from a YSB-12 work on a YSM? Any suggestions on where to get parts for this? is it even worth rebuilding? Any suggestions/opinions are appreciated.
