Afternoon Gents and others...<br /><br />Can anyone tell me if the engine in a 1988 Four Winns 200 5.7 Cobra has a one piece rear main seal or not. Also if the cam is a roller or flat tappet.<br /><br />I believe this boat, even though it last came from north Texas has seen a lot of salt, plus, though it runs good, it has "way" too much blow by for me...So I'm considering an engine change. I can get GM crate engines in the money and don't want to get into any flywheel problems.......Or any other problems if anyone has any tips. (Assuming that using the marine carb, alternator and starter..is a given)<br /><br />I believe that the truck engines have a similar cam if my information is close to right.<br /><br /> Also what should be done in regard to the outdrive as far as checking for salt damage...I have zero experience with anything but fresh water boats.<br /><br /><br />Thanks..Stan
