Re: Rebuilding Yanmar 3GM30F; need advise $?
A completely rebuilt 3GM30F can be had for $5,500 if you have a core, and that's a RETAIL price.
You need to be careful with that term 'rebuilt'. It will pay you to ask for specifics on what is meant by 'rebuilt' since the term is subjective. In my world, 'rebuilt' and 're-conditioned' are two very different scenarios.
Rebuilt should mean returned to factory specifications in ll respects. You should get a written warranty without asking on a 'rebuilt' engine.
