I'm still sorting out the boat we got a few weeks back. It's a 1962 Sakonnet with a 1998 60 hp Merc 2 stroke.
The prop is in ok shape but I thought I'd do some research on it. The number stamped (molded in) on the prop is
48-73144A40 - according to the Merc manual, this prop is for boats up to 15' weighting up to 1000 pounds gross.
So, our boat is longer than 15' and I'm rather confident that the gross weight is way over 1000 pounds.

How much of an issues is this potentially wrong prop? What am I loosing/hurting with this prop? What would I gain with a properly matched prop?

Thanks in advance!
