Members have learned that prop size and performance are not universal across brands.
Why the 4 blade? They are good for quick time to plane and heavy loads (like pontoons).
If you are looking for speed, change to a 3 bladed stainless steel prop. If not, go with the same make and model prop you have with 2 more inches of pitch.
If the engine is mounted up 2 holes and you get the right 3 bladed prop I would not expect you to see more than 32 mph with a 35 hp motor.
If you raise the motor to be dialed in, you will gain ~150 rpm's at WOT for each hole up you go so do that first.
