Propco Prop Efficiency Gains

[jhutches]

Has anyone worked with the new Propco Slingshot props? They are designed by Peter Dean and he has a pretty good reputation. I do not know enough about them to make a determination.

But they swear they will give you a 40% gain in gas mileage over a cupped prop design. This sounds a little far fetched.

Anyone know if this is for real?

Thanks,

Jerry

No I dont, sounds interesting, like to know more.
His web site doesnt have the hyper link on 'slingshot'?
Last time i spoke to Peter has was OEM ing some props for Merc.
As an accomplished racer he knows what he is talking about.
40% doesnt sound right
(He had the Propco business in Melb OZ before he moved to the states thats how I met him.)
