Looking for a SuperCat crank
I'm searching for a short-stroke (3.829") Callies Lightweight crank for Merc Supercat motor.
Anyone have one of these lying around? If so, please call me at 313 283-8148.
Thanks in Advance,
Brian

Ok, so I'm extending my search criteria... looking for a GOOD crank, with a stroke up to 3.875"
Apparently, those short-stroke Callies cranks in Supercat motors are an oddball cut, and I've broke two of them anyways.
Number is above if you can help.
Thanks,
Brian

Have you tried JCPERF?
May wanna look at getting the block line honed if it hasn't been already. Seem's weird!

Weird? Sure is. If was the same motor, I'd be looking much more closely at the block, but they broke in different motors. Yes, they line honed them just to clean up crank bores.
Both cranks broke this season. Any ideas what causes a crank to break?
Thanks,
Brian

Leave it to Mercury to come up with another oddball engine part. They could've used 427 cranks (3.76 stroke) instead
