Title: McCoy Propnut threadsize
Post by: Timothy Payne on August 04, 2014, 04:25:58 PM

OK, heres one for yer'all!

Upon recently acquiring a half-decent McCoy 35, everything is present on the motor except for the correct propnut! - What size are these crankshaft threads (I'm guessing UNC10-32 or 24 possibly).


I'm sure a few of you know this,
