Thanks but that was of no help I'm a master mechanic and I'm aware of the specialized marine parts for safety lol Not to be rude but please read the questions. in my question I stated that I'm aware of the marine bolt ons like starter at ect... And simply wanted to know how to adapt everything on the out drive

I'm only asking about the swap. Even if I went and bought a marine ready gm motor it won't bolt to the out drive my question is I know I need the bell housing but will the gm manifolds bolt on the y pipe that the ford used? Flywheel adapter to bolt shaft on? Motor mounts are different but I found adapter mounts.

I've decided to stay with ford. Replacement parts seem easy enough to find thanks for the help.

your boat so its your call.....I did read all of the post....I try not to reply to threads unless I have a good idea about what the issue is and if I think I might can be of help.....we have no way of knowing your skills or background, especially being a new poster.....the forum members simply respond to posts based on the subject being discussed to offer help....being a Master Mechanic you know more about how engines and drivetrains work than I so I can't offer any help there....from your last reply it seems you may think the only difference between a marine engine and automotive engine is just the spark containment in the electrical components of a marine engine for safety concerns.....this is just one of many differences between the two.....a marine engine is designed for longevity while being run under constant load for long periods of time....there are also many corrosion resistant materials used in marine engines.....your mind seems to be made up on using the Ford automotive engine so good luck with the rebuild and install....you mentioned you want to pass the boat down to your kids someday....hopefully the boat won't need a new engine when that time comes....

Lol no it is a marine 302 I'm replacing the old 302 with. I'm being told go gm. I know the difference there are many all the way down to the pistons.

My question was the mounting of the gm motor. I tried to specify that I'm not asking about the block or comp on its just putting it in. If I went gm it would be a marine ready unit and all I would need is the mounting figured out.
