Ryan, is it possible your water pump is off an old 12A?
Lynn Hannover is on this list and would be able to answer anything about 12A's ... maybe reach out to him directly in the subject line??

Hello Ryan, this is a photo of my water pump from a 1988 13B ...  Jeff


All,
        
Can anyone point me towards the correct water pump? The one in the top of the photo is the correct one. The one on the bottom is obviously incorrect. It's the second one we've ordered.
The first one that I ordered looked identical to my original one.  However, when it arrived it was similar, but about 1/3 smaller than mine. When I ordered this second one we all (Carquest employees) poured over the pictures to make sure it was correct. When it arrived it had one less bolt hole than the one in their pictures.
I have a Powersport 13B. Any ideas what pump they ran and where a guy can order one

Thanks,
Ryan
