Opposite rotation motor smaller starter

Hi Gang,

I'm working on a boat with twin carbed small block Crusaders of 2003 vintage. Both motors appear as new and both starter motors are painted Crusader blue. I noticed that the Stb or opp. rotation motor cranks slower than the port motor, but cranks ok. The slower cranking Stb. motor has a much smaller starter motor. Whats up? Does'nt GM make a large opp. rotation starter? Or is it that when turning a motor in the opp. direction it's normal to crank slower than the standard rotation motor?



Thanks Guys,
Jon Allen

I don't think GM makes starters any more; buys them to their specs, typically from the lowest bidder. Many players in the market now so finding several 'size' options wouldn't surprise me.

As far as the full size versions, they can be made to spin either way, electrically, with little effort. Finding the correct drive takes a bit more effort. There is usually a repair shop in every major city that can do any rework, usually in a day. Several smaller shops used to exist but are getting harder to find.

As far as speed, it should be independent of the size of the starter. I'd be more inclined to suspect a low voltage condition somewhere in the wiring. A clamp on amp meter is a great tool, if you have one available.
