Wondering how to figure out what starter to buy to replace the starter from 1987 260 HP Mercrusier I/O. If engine rotation is specifed as CCW does that mean the starter must be Clockwise or Counter Clockwise? Also can't seem to figure out what engine I have. Can not tell if 5.0 or 5.7L. Is there a Web site where you can enter your Engine Serial Number and get info about that engine? Sticker on engine just says 260 HP 350MCM. But parts stores list just 260, or 5.0 and 5.7. Please Help<br /><br />Thanks
