I have a 2000 Bravo III which currently has a seized up 7.4MPI.<br /><br />Displacement is 7200 pounds on an express cruiser hull. (Doral 270 SC)<br /><br />I would like to repower with a different engine, perhaps one the 350 blocks that put out similar horse power as the 7.4's 310hp.<br /><br />Has anyone else performed this feat?
