Help me choose a prop

[Wangs]

 Hi. I need help choosing a prop 2021 Axis A24 LT4 use only for wakeboard

Ballast setting est. 5000lbs / +6 people inside boat

17 x 17 2800RPM =22.5 Miles

17 x 14 3200RPM =22.5 Miles

17.5 x 13.5 3500RPM = 22.5 Miles (Approx.)

lf we use the new 1 7.5 x 13.5 prop, we think it will be used at approximately

3400~3500 rpm For wave size, the 1 7 x 14 is probably better suited ijnmy perspective but the 17 x 17 is probably better for better fuel efficiency.

If we ride the boat at lower rpm, dont you think it will overwork the engine? (Just our thought)

If we are to use the new 1 748-MF 17.5x13.5 prop, we think the estimated rpm will be 3500.

Do you think to have the cleanest and best wake, the new prop will be the best fit? 

and one more at now setting What is the appropriate rpm for lt4? thank you)
