thanks for answer captain,
I think I will go for a new engine-transmission.
Estimate here in Montreal are 10 000$ to rebuilt westerbeke 4-107 and Paragon P-24 tranny.
New engine is around 13 000$
I'll check for a 56 hp Yanmar with Kanzake tranny. Did it bolt on when you did installation?
Do you think that more then 56 hp will get you more power or its not needed? If a add a high amp Balmar alternator and freezer compressor?
