FAQ

What exactly is the task / function of the component?
The propeller converts the torque supplied by the drive into thrust and at the same time influences load absorption, acceleration and achievable engine speed. Geometry, pitch and hub connection are therefore system-relevant.

How can you recognize a defect / typical symptoms?
Defects are indicated by vibrations, uneven running, loss of thrust, cavitation, bent blades or a spinning hub. Scrapes and asymmetrical blade edges also impair efficiency and smooth running.

How do you check / test the component?
Blade condition, edge damage, concentricity, hub, gearing or hub kit and correct securing on the shaft are checked. You should also check whether the motor speed is within the intended range, as incorrect pitch causes similar symptoms.

When should it be replaced?
The propeller should be replaced if there are cracks, significant blade deformation, a worn hub or permanently incorrect load characteristics. Minor damage can be repaired depending on the material, but serious structural defects cannot.

How do you check compatibility?
The OEM number, diameter, pitch, direction of rotation, toothing or hub system, material and clearance to the transmission unit are important. The propeller is not compatible without a suitable hub kit or correct securing.
