Our 1982 C&C 30 is fitted with an Atomic 4 and this past summer we experienced motor problems such that at haul-out, on the advice of a mechanic, we had the motor removed. This past season we would not have used more than a tank and a half of fuel. On the other hand, pending what might be wrong with the motor, I have been exploring a diesel replacement as opposed to a rebuilt A4 from Moyer Marine. I would appreciate hearing from any other C&C owners who may have faced this situation. If we go to a new diesel, the engine of choice would be either a 16hp or 20hp Beta.
