Like new still in box, used less than 30 minutes trying to figure out the proper pitch for my pontoon boat, bought 3 props in 3 weeks. This is a Hustler made by Turning Point. Will require purchase of hub kit applicable to your motor, can use Turning Point MasterGuard hub kit, Solas Rubex, Michigan Wheel XHS, or Mercury Flo torque ll hub kit. I settled on a Hustler Prop discovering they performed better than two Yamaha oem props I tried. This prop gives great low end torque and gave me 6200 rpm at wot on my F115 Yamaha. That yielded a speed of 19-20 mph, my boat is heavy. Again, prop is as new.
