I've always used Mac Boring for parts I can't get locally, and for
repairs I can send out. They rebuilt my transmission when it failed,
and have reconditioned my injectors a few times.

Eventually, you will want to have your injectors reconditioned. Its
easy to pull them - the hardest part is getting the precombustion
chambers out - and send them off to be redone. All the small parts
including the chambers should be replaced, including the chambers if
burnt. You can send them off with the injectors and let them decide.

It is a Yanmar 2GMF, freshwater cooled. What
maintenance do I need to do? It starts and runs
nicely, no problems, just preventive maintenance.

It has seen very little use over the last years,
and probably not too much maintenance either.
