*freestyle innovations recommends = d-75, 7/12

*and i have also heard (dyna fly 12/22)

It really depends on what you want your boat to do if it's strictly a flatwater freestyle boat you need the lowest pitch prop you can use I run a 967 with 155 oem pump pfp tl ect 5/10 prop big hub which was not the motor builders recommendat ion but worked the best for my setup purely looking for bottom end

 

[Chris V]

thank you. so the first number is for low end and the second number is top end? so a 9/16 will hit harder than a 10/16?

 

[jonolove]

The first # is the pitch of the leading edge the second is the pitch at the back of the prop it's a variable pitch older single pitch props will only have one number like 14 or 15 this would be a single pitched prop my recommendation is to talk with impros explain your setup and start with their recommendations

 

[jonolove]

You can still achieve a huge bottom end hit with a higher pitch but you need a lot of power

Know one here is going to be able to tell you the perfect prop. It requires just getting something close and then a tuner to hop on Your specific ski and make adjustments to the setup.

SB-pump, SB-prop, cone size, reduction bore, nozzle bore, pump tunnel design, hull weight, and that's just for the back of the ski, then add in everything under the hood and you can quickly see why it's not as simple as what prop, it's mearly just a starting point that's why you see different numbers depending who you talk to.
