Default Re: Prop Slip Calculator

If and I think it is - my gear ratio is 1.87
Stilletto 19"

Then at cruise 3400 I'm at 14% - 27/28mph

amazingly at 4200/4400 it drops to 10% 38/39mph, it stays about there at WOT
Motors too low also would like to go up 2 holes - only get 5300/5400 would like 5600/5800

Thats also with the Big Ol'Fat Houndog( 100lbs) sitting in the bow with ears a flappin - can't get him back when I go fast either, no matter how many times I try and explain the speed factor and getting the bow up

I have been very happy with this prop, amazing trim response and makes the boat ride very dry - other one was very wet, actually very very wet. Never did the slip before though so guess I'm happier

Beware it is very aggresive and will knock down the RPM, I had a 19 on it and it took off a solid 300 RPM for the same size.
