Best store for boat prop advice?

[lakepowellnut]

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.

I've seen this topic come up frequently on other boards and Mercury's prop calculator tool is a go-to for many. I know I use it frequently. It's a good starting point to narrow your selection. The cool thing is it covers more than just Merc's. To avoid costly purchase mistakes, I look to this calculator.
