Hi all. I have a 1989 Four winns 200 horizon. I'm getting ready to start rebuilding her. She has an OMC 5.7 COBRA 260hp with a cracked block. I have another block to build. Here is my question.... I also have a 1989 sea sprite with a Mercruiser 5.0L 230hp with alpha one sterndrive. (See older post). This engine is possibly (most likely) locked up. What are your opinions on swapping out the OMC for the Mercruiser? And why?
