Best store for boat prop advice?

[Bassin_Blitz]

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.

You need to reduce pitch not diameter, Bear lake is close to 6000 ft willard is 4200 ish for every 1000 ft you would drop 1 inch in pitch so you would want to go with a 15 1/2 by 11 assuming you are already set up correctly.
