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.
