Hey guys, I have a 15ft tri hull i am building and I had just purchased a mid 70's Merc 80hp short shaft thunderbolt.The prop is really banged up and want to replace it and tune it up before I drop the boat into the water in the next few months. It has a factory 2 blade prop on it measuring about 13 1/4 diameter, unsure of the pitch. I can't read the markings on the hub. Does anybody know or have a rough idea what kind of factory prop came on these motors? Thanks
