The blades are then luster polished to maximize propulsive efficiency.

High speed boat propeller. Although attaining speeds up to and in excess of 100 mph on tarmac is not an arduous task it is a rather more multi-faceted undertaking on water. Handling minimal steering torque and outstanding top-end with the T-3X Comp. We have to choose which of them we prefer more depending on the use of our boat.

45 MPH The Gear Ratio between the engine and the prop shaft. In most applications a Pro Finish propeller will deliver more RPM and higher top-end speed than a standard production propeller. The engines RPM at WOT.

If you still arent sure give us a call 1-800-998-9508 and one of our techs will help you find the right boat. The higher the speed of the boat the higher the pitch should be. At 80 MPH with about 6 prop slip you would be turning a 12x15 3 blade 5991 RPM.

They are engine RPM prop gear ratio normally for 15 to 30 prop pitch the distance that a propeller would move forward in one revolution prop slip the efficiency of the prop lower at high speed but perhaps very inefficient at low speed and the boat speed in mph.
