I have a 97 90HP Yamaha and would like to put a SS prop on it. I looked on Yamaha marine parts finder for my prop, there are a few different options for size, 13x19 13x19 13x21 and so on I know the 13 is diameter, but the other one is pitch, what does the different pitch do. What would be a good size to get, my boat is a 97 skeeter 16'3" Thanks
