It MUST ABSOLUTELY be a marine alternator. DO NOT try to replace it with an automotive type. Marine alternators (and other marine parts) are designed to reduce spark, which automotive parts are not.<br /><br />In any case, Overton's should have a replacement. Look for some part numbers and/or amp rating on the old one.
62-65 amp in most cases you can use up to 70 amp<br />that will bolt up if you have a nando( ??) you can replace it with a delco but the main thing <br />it must be for MARINE USE !
here's where I bought mine a couple years ago,<br />haven't had any problems with it although you may want to paint the outside of it when you get it otherwise it'll look like crap after 1 season.<br /><br />I have a model 233 merc with the 351.<br /><br /> delco 10si 2 inch foot
