I am really hoping I am doing something wrong. I purchased a new (to me) stainless steel prop this winter and am just getting around to installing it. I am putting it on a Mercury 115 Optimax. After taking off the old prop, cleaning everything up and doing a test fit, I noticed that the end of the prop that is milled down to slide into the motor does not fit! It is actually the same diameter as the outside of the motor opening. A picture is attached.
Do they actually sell different diameter ends for props and I purchased too large of one for my motor? To make maters worse, this issue is also causing the prop blades to come in contact with the trim tab.
Any help (good or bad) is greatly appreciated! Thanks.
