Can someone explain what "pitch" is and how it is calculated? Is it degrees from "?" or what?

Also, higher pitch number like 20 equals better or worse hole shot? 20 being compared to 14...

14 more hole shot less top end higher rpm's if your rpms are close to the limit you usually get a "higher" pitched prop.

"pitch" refers to the distance the prop will travel forward in one revolution. So a 20" pitch prop will move 20" in one revolution (it's actually less than 20" due to losses)

Higher pitch = worse hole shot IIRC

Prop pitch is easiest to think of as the number of inches the prop would move in one complete rotation. so the angle of the blade if turned 360 would provide so many inches of forwards movement.

with the prop on your boat it actually doesn't move forwards that amount because the water slips.

But if the water didn't slip your boat would move forwards the exact distance as the pitch for each rotation.

Fake ideal water that doesn't move in relationship to the surrounding water would do that.

I was told prop pitch can best be explained that if you set a prop in a huge bowl of jello the pitch is how far in inches the prop would go into the jello after one revolution!!! Here endith the lesson!!!:D By the way is that a tatoo, that had to hurt!!! :cry:

Grape Jello gives ya a better holeshot than Cherry Jello and I think Pink Lemonade Jello is exclusively for wakeboard boat props!:rolleyes:
