Good morning all. I have a Cabo 40 express with the C12 Cats. Port engine moves about 3/4” forward when throttling up. Upon investigation the fwd inbound mount flexes significantly. Couple of questions. As I understand Cat has upgraded the mount to a 1” stud instead of the 7/8” that’s there now. This would create a problem to drill out the hard mounts without lifting out the engine. Has anyone faced this issue? Can anyone give me a source for the mounts? Last but by no means least, the stud seems to have a “lock but” with set screw. Is that to tension the bushing or to prevent the stud from rotating? Looking forward to feedback.
