I have a 21 foot seebold eagle with 5.7 mercruiser 350. Can anyone tell me what the factory prop specs should be? It has a ss 14.5x22 on it now. Boat has no bottom end power and takes forever to plane off. Once it planes I cant trim it up much before it porpoises like crazy. I can also tell that...
Just bought an 1988 Seebold Eagle with 5.7 Mercruiser 350. It runs ok but has no bottom end power and takes forever to plane off. When it finally does it porpoises really bad if I try to trim up. This is my first i/o and not sure where to start. Thank you
