 How to measure a three blade prop I have a 27hp prodrive gen 2 with original 3 blade prop. I bought it used guy told me it was the original prop.
I have searched everywhere and can't find out how to
Measure prop to see if it's worn and if anyone knows what size it started as.
It's a stock motor and I get about 18mph with two guys. 1651 Phowler extreme boat
Thanks

Re: How to measure a three blade prop Center of hub to end of one blade. That's the radius. Double that.

Re: How to measure a three blade prop It is not the diameter that matters....
As a three blade wears the blades wear most in width....
PD liked the GD 3 blade which was 3 1/2" wide across the blade when new
still ran well at 3 1/4" but was worn out at 3" and useless for loads or speed...
I wear out a 3 blade by 50-70 hours FYI
