Specially designed for sailboats and other displacement craft, Yamaha's patented Dual Thrust propellers are built to handle the job of pushing heavy loads through water. The hub is carefully designed to redirect exhaust flow away from blades, so Dual Thrust models cut through "clean water" for higher efficiency and better acceleration. Thrust is improved up to 70% in reverse and 10% in forward.

For pushing a heavy load slowly, go ahead and get one if that's what you want to do.

Since I have no prop on the motor and the guy will let it go for cheap ... It will make a good Spare when I DO get the one I really want ...

I think the gearing is different in a hight thrust motor. It might not be good for the motor.
