I posted a thread on the local fishing forum, looking for a prop. Already got a call, a guy has a 14-1/2x17 OMC stainless prop and wants $100. Might get it after i get my trim motor.
I took my prop to Accu-Prop. Found out my 15-1/2x14 is way too big for my engine for what i am using it for. Also one blade is a 13 pitch

and on top of that the previous shop i used for my prop repair put a 8-10 cup on it.

The owner of Accu-prop said that 15 1/2 prop is primarily for 250s and maybe the v8 300. I guess when i originally bought the boat 4 years ago they stuck any prop they had on it.
