Repower for the 21st century

Rebuild a 1979 Yanmar 3QM30H (raw water cooled)?


I went the repower route on Far Cove (story is at
http://www.bcboatnet.org/Tech/engine/index.html )

There are SO many things apart from the engine itself to consider: exhaust
system. Control cables (mine broke just as I was replacing them!).
prop/shaft/stuffingbox. And so on.

I put in what was supposed to be "like for like" and still had to redo the
stringers twice, completely redo the exhaust, and so on. If I had gone the
rebuild route, I probably would have done the other upgrades as well.

Now, Far Cove was substantially underpowered with the original 23hp, so
the 26hp was a good upgrade. If the replacement was the same hp, I
probably would have just rebuilt.
