MerCruise 7.4 , rebuilt to a 496

This is a 7.4 , 454 big block.   Water ran down into carb and locked this engine up.   We removed it and had it rebuilt to a 496.   This engine went from 330 stock hp to 525 hp.   We did end up changing out the holley carb to a built webber.

Alpha 1 Gen 2 Gimbal Bearing Frozen

This is a alpha 1 gen 2 drive , gimbal bearing is frozen and it wont come out !  We tried to pull this bearing for about 45 min.  , we then went to drilling it and pulling it out in small pieces.  We then had to repair the upper shaft bearing because the upper nut was not tightened by the last boat repair shop !!!!
