Let the debate begin........

Repower for the 21st century
Or
Rebuild a 1979 Yanmar 3QM30H (raw water cooled)?

Lets assume the engine is DOA and must be either replaced or rebuilt.
My first experience with replacing an engine was attempting to shovel a
huge Cadillac engine into a Nova. Boys will be boys. Lesson learned:
Lots of adjusting and cutting. But hopefully those who have actually
repowered a 34'-41' keel boat learned a few lessons from their
choice.

This is not a troll. I seek your advice with the greatest sincerity. So
be brutal or humble or descriptive adn I'll gleen what I can.

After reading my latest issue of Boats & Harbors I wish I had a 6-71.
Either way it would be cheaper than my little 27 hp Yanmar. Go figure.

Cordially,
Bob
