Our speed boat propellers are approved by CCS ABS DNV BV NK KR GL etc.

High speed boat propeller. One of the many considerations of high-speed marine applications is transmission and propeller design. The SuperCrew is a high-speed boat propeller that has been engineered to run with ease under heavy loading where efficiency and vibration reduction are top priorities. The first is pitch the theoretical number of inches a propeller moves a boat forward with each complete rotation.

Gear ratios are typically used to control pitch and manage power but. 45 MPH The Gear Ratio between the engine and the prop shaft. The same propeller can not achieve both the highest top speed and the maximum acceleration.

Or if you have the OEM propeller number you can enter that in and it will give you the Solas cross-reference. Planes at a lower RPM. Enter any 4 variables and the 5th variable will be calculated.

Also the higher the pitch the greater the efficiency of the propeller. Higher pitch can be used by selecting higher gear ratios but this is not really viable for most outdrive powered craft due to the small choice of ratios available and in this case it is usually necessary to work with the supplied ratio. We will offer the certificate per as customers request.

VEEM propellers are 100 CNC machined to hair thickness accuracy over every square inch of the propeller including the boss and high BAR overlapping blade propellers. Safer stronger and more durable. Assuming your 17 boat is a fairly lite racer lets say 2000lb with fuel and driver and your 380HP is brake HP.

If your prime mission is to move crews and widely varying loads as quickly as possible the SuperCrew is a great propeller to consider. A High-Speed Boat Propeller. One way to compensate is by using a prop with a reduced pitch.
