40HP Scott Atwater 1957

[joesnuffy]

I have a question on this motor. I am finishing it up and only lack re-sealing the lower unit. Can someone tell me what the part number is for the prop seal I have in the picture and where I might get one. Possibly a substitute?? part number I think the motor is around a 1957

Thanks,
Joe

If you measure the shaft diameter and the bore diameter the seal is pressed into, you will likely find something at the site below. If you can find a Scott part number, and if Chicago Rawhide made it (which is very likely) the 2nd link below is the manufacturer’s cross-reference site. Chicago Rawhide is now SKF.

As a last resort, it looks like there is plenty of room to fabricate a sleeve to fit a smaller seal OD. Don’t overlook stock outboard seals–generally made of stainless steel. Sierra has a chart showing sizes.

Joe,
I’m in Az & went to State Seal in downtown Phoenix. They matched my Scott seals & had a double lip seal too + No shipping costs,

Thanks Gary and Jeff.
