Rated 4 out of 5 by Eroc1 Bang for the buck
Good product. Great performance. Only complaint is pitch is not matched inch for inch on 3 blade to 4 blade props. Must use a lower pitch prop to turn the same RPM'S when going from 3 to 4 blades. I have to return mine and choose a different product. They don't offer a pitch suitable for my 22ft pontoon.

Rated 4 out of 5 by teda backup or main prop
Installation was no problem except I had to add a washer (really a machine bushing) to get the cotterpin hole to line up with the slots in the crown nut.
My OB is an F40 Yamaha. compared to my 3 blade Turning Point screw, I got a better hole shot and more power to haul a load and climb boat up on to the trailer, but I lost about 5 mph top end. I have not hit anything yet, so cant comment on durability.

4.3 liter Mercury I.O. which composite prop would work best?Answers
Top 250 Contributor
A:
19 pitch
A:
To find the correct prop you will need to know the HP, Year, and Diameter. The pitch would be 21.Answers
A:
depends on what you are doing with the motor. what size boat the motor is on and what you want to do with it ie, fish, ski, joy ride. in most cases, you would not want to use smaller than a 15 pitch or higher than a 19 pitch. the smaller the pitch the more load and torque you can have but less speed. The higher the pitch, you get more speed, but less pulling ability.

You will need to know the year, diamter and pitch to find the best prop.Details:
Spacers, bearings, washer, nut and cotter pin?Answers
A:
No this comes as a prop only.You have to use your old hardware.A:
No, the prop/hub are one piece. I had to remove my existing splined spacers (front and back) and used my existing flat washer, castle nut and cotter pin.
