I went that route before with a one cylinder 1982 yanmar. It cost me $3600
CAD to have the engine overhaul. After 20 hours of running time the crank
shaft broke in two. I am still trying to get it fix under "warranty". The
guy that overhauled the engine said that it not worth spending any more
money. I have learned a lesson the hard way. A rebuild, overhaul, or
refurbished 20 years old diesel engine could turn out to be a nightmare.
The new components may be of quality but the engine block may not.
Plus the warranty on rebuild engine (If you have a valid one and if they are
willing to honour it) is in days whether the boat is at the dock or not.
FWIW

Yo ,, Bob... $6,000 for a rebuild of a motor? Something is wrong with
this
picture.

I've priced out a few sailboat aux's recently. I think the price for a
new
one was around $5,000.

Yes, I agree. I walked into a local John deer tractor dealer and made
the mistake of starting with, "I have a sailboat...." Actually the
quote was $5800 and some change.

i just did some more searching and found a rebuilder that has two
3QM30H RW for $4400 each. But rebuilds do differ from shop to shop. But
the tractor quote did seem way out of line. Another factor to consder
is the QM weighs about 750 lbs! I under stand the newer models run 1/2
that. Maybe more room for fuel??? Nah, rum.
