Gilly -

Correct - i have them backwards 13 3/4 x 15 and 13 1/4 x 17.

My boat is a pretty light rig. Overall, the performance is pretty remarkable. I come out of the hole with little to no bow rise. Probably because my tank is forward, and my console is a little forward as well, with no front seat. On plane the boat runs very flat. I think my only need for tabs would be to adjust side to side or slowing the planing speed.

I can stay on plane down to about 16 mph. I can cruise all day long at 4000 - 4200 running 27 mph. @ 4500 i'm running 30 mph with another 1000 RPM's to play with. I haven't checked my fuel mileage, but i've put almost 7 hours of break in time on the motor and have not put fuel in the tank yet. Filled it up on day 1, almost 55 gallons.

I'm very interested to see what happens if i throw 4-5 people on and a sandbar type load with coolers and such.

If i find a few extra pennies, i might move up to a stainless powertech and see how it runs. You'll probably see some aluminum props in the for sale section soon.

ESD - when you say 300 RPMs on the stilletto, is that 300 up or down for the same pitch? I need to shave some RPMs i think. I can run my 5500 RPM redline with more throttle with a 15p aluminum black diamond.

"Performance is pretty remarkable."
I told you so Feels powerful, yet nimble, huh?.

Yes, somewhat, but actually more credit for this is due to the prop geometry. That is what that prop is designed to do. IMO, it does it like no other aluminum prop.

If you go stainless, stick with the shape. PowerTechMQF3R15 for your motor. You can find'em for about $270.

Side note, ESD's prop has more progressive rake and cup making it harder to spin and frankly you lack power to get the most out of a Stiletto or Turbo. IMO, it's just not the right shape for 115 ponies on a 2500 lb 20. Just looking at the Stiletto I think you would need at least 150hp to move your load right with that wheel.
