Thanks for all the input ! I ran the numbers and its a Gen IV 502. All my stuff is gen VI so I didnt get it. If any one is looking for this type let me know. It was a crate motor and has never been apart,I got it started and it ran fine. The boat is junk. It has trans too.
Thanks again

You can run all your gen 6 accessories. Just install a fuel pump block off plate. The gen 6 engine does have some improvements to the castings affecting oiling and cylinder cooling I believe.
