And I think folks can understand the downside to diesel
engines on a sailboat. For many weekenders and short distance cruisers, running a diesel engine
just long enough to get out of the marina and setting the sails
and reversing at the end of the day isn't the best way to run a diesel engine.
It's all about perspective and usage. The OP has a vessel that is 40+ years old. Great hulls they built back then. Mine Pearson
was built in 1962. Bullet proof. I have the original A4 - untouched. Since I am in fresh water
, the engine could last decades just as she is. Fresh water cooling
can also lengthen the life of any engine. However, spending 10K on a 40 y/o sailboat makes sense if you are going on a long cruise
and want that fresh reliability
that comes from a new engine. Hell, a 40 y/o sailboat isn't likely to be worth much more than that even in pristine condition. Once you put that new diesel engine in a 40 y/o boat worth 10K you will have increased the value of that boat to, say, 11K. Replace it with a rebuilt Moyer A4 and the boat will be increased in value to, say, 10K.
Don't put a diesel engine in the 40y/o boat if you are thinking it will increase the value any appreciable amount. Put it in if you are going to cruise
far far away.
If you can get her to your uncle in FL for some help, do it. It'll be fun.
