Best store for boat prop advice?

[wyoguy]

Looking for a new or rebuilt prop for my 90 HP evinrude. The one I have does alright at Willard but not so good at Bear lake, the RMP's are not going up as high as they should, especially at BL, so I was thinking that a smaller prop would do the trick. My prop is a 15 & 1/2 x 13, I was thinking a 15 x 13 might do the trick.

A Roc in SLC is the best as far as I'm concerned, they can tell you over the phone what you need, and if they have one.  Sell new and rebuilt.
