Shane Mark did a 2717/19* prop for me and I ran it on my ML sport hydro, granted I ran a full mod 26 but the boat preferred it over other props it was quicker to accelerate and settled the boat down. This was in race set up not all out speed. I would listen to Mark and try his suggestion.
I dont race, so I just need a good prop that has a balance between good handling and good speed, and doesn't over load my Alpha Evo engine, I not eanting to break any records,
I found a really nice Stainless 3BL prop I got from Andy a few years ago, along with a couple of Prop Works West 3BL gas props, so I might try those first
