ProPulse Propellers and Sting Ray Performance System

[chuckatwestmarine]

I think the point is that buying a propeller can be a bit of a trial and error process. Some boats do come with the exact right prop from the factory, but I have owned boats that were mis-matched, and it's taken a while to get the right pitch. With the ProPulse, you can adjust the pitch in small increments to find the exact right setting. I have also trailered my boat to Lake Tahoe, which is at 6229 feet. Due to the thinner air (something like 18% less available oxygen), I have to reduce pitch.

Hey Chuck wouldn't buying the right prop and trimming the motor correctly work instead of that garbage ?

now your gas mileage sucks!

One of the better videos in explaining, and not a sales pitch like the other videos on this website. Thanks for the education on prop physics.

No demonstration or talk of cost. yeah, let me run right out and buy it. Pffft.

Thats a cool system!

I like the prop and how it s made.. as a pilot: we have composite props for aerobatic..

that prop seem quit shabby. any system like that with a lock screw if bound to fail.
