[Public-List] Replacement Engine

[Jim Davis]

Tom

Also it would help to know what your boat's hull number is.  The older boats 
with the wooden interior will accept a wider range of engines than the ones 
with a fiberglass liner.  In either case, if you are going to go with a 
diesel you can expect to have to modify the engine beds to accept a diesel. 
Whitby took a few short cuts that make direct bolt in replacement difficult. 
As Mike Lehman pointed out the Beta is a good diesel to use in either style 
boat.   Westerbeakes are also a good choice, however more expensive.  In the 
small sizes both use the same Kubota block.  In the wooden interior boats 
you can use a Yanmar as well.

If the price of a diesel is too high, you can get rebuilt Atomic 4's at 
reasonable prices and they will essentially be a bolt in replacement.  Moyer 
Marine is a good place to start if you choose this route.
