Re: prop pitch?

Pitch is how far forward a given prop will travel, in inches, in one revolution with 0% slip. The most accurate measurement is with a very complex laser machine. It's really hard to measure props today as they are all progressive pitch.

There was someone who posted a proceedure for manually measuring on a while back. It really didn't work for me but some other folks said it did for them. But I was measuring a Turbo which has a pretty complex shape.

Re: prop pitch?

my main thing is i want to know if this is the stock prop and if it is what i could go with to make it a little bit quicker on the top end

Prop number or size is usually on the barrel of the prop or under the nut.
-- X -- or a reference number.
Give us your present prop size/description aluminum or stainless,max rpm and gps speed.you can also fine tune your setup to help speed.
