I had a 19 ft Cuddy Cabin with a Chevy 250 Marine engine that I had rebuilt. Rebuilder said the marine engines were different in many ways as they were built to run at constant high rpm and make most of their power there so I wonder if a marine engine would be appropriate for truck/pickup use. The 250 was plenty of engine for that 19 ft boat. It went away when I bought an acreage and traded it for an old Terratrac (Case)bulldozer to clear land.
