Re: Mid seventies 105hp starter motor.
ebasic sells one for $159 part number is ARC7325. Mercury sells one also FK616955 for $227. Before you buy a new one you should take the old one apart and see if cleaning will fix it. If you take it apart and the brushes fall off or burnt then it is junk. WD40 and a bunch of Qtips turned mine into a new starter. Chrysler built things pretty solid back then. The biggest trick is getting it back together again. I use mono fishing line and tie the springs and brushes back in place. Once the cover is over them cut the fishing line and pull it out then finish closing the whole thing up.
