The time has come where the Yanmar on my 1979 J30 needs a rebuild. The power is not as stong as it once was (a stiff headwind and waves can make a very slow situation) and seems to be burning oil. My question is, has anyone paid someone to pull the engine, rebuild and re-install? Any idea what a job like this might cost? Just looking for a comparison number as I find the right Yanmar person for the job.
