Poorsche

I was re-organizing my garage and found these "cleaver" like props. I've currently got 21P Mirages on a Formula SR357 and I'm only getting 4000RPM at wide open throttle.

Can anyone predict what some of the effects of putting these props on will be? Pic is of just one of the props--gona put LH and RH on TRS drives.

I think my new drives are longer than the ones I replaced and X-dimension is "longer".

Thanks for any comments.

A friend had a prop like that on a small Checkmate. I think the person he bought the boat from just put it on there to get rid of it. It did not run that well. He switched to a Mirage Plus and picked up 5+ MPH. I think they only run good on certain boats.

It'll take you 5 minutes to swap them out with the other props at the ramp. Try 'Em out!!!!

Gave the change out a try--adn might know--the thrust washer for MIrage is totally different than for the cleavage prop.

Now to ID the correct thrust washer and another shot at it.
