iboats.com has a prop section to purchase a prop.Just put you motor in and the props come up.Pitch is the main thing,got to get it with in rpm of motor. Ex.a mercury 30 comes with a 9.75 X9.5 wheel.This is 9.75 in diameterX 9.5 pitch.S S is a 10 X10,which means 10 diameter and 10 pitch.The First number is how big wheel is the 10 will fit where the 9.75 was.I went to a 10 pitch from 9.75.To much pitch will slow you down,if you cant swing it.

If you look on the prop near the base of the blades or under the prop nut there should be some numbers. _ _ X _ _ diameter X pitch.If you read the stickys at the top of the page and the helps on the prop store page,it will help with prop selection.We're here to help you through the confusion.
