You can often repair a spun propeller.
A spun propeller, where the blades no longer have the correct pitch, usually requires repair or replacement. Minor spins can sometimes be corrected by a qualified technician. However, significant damage often necessitates a new propeller. Inspect for cracks or bends before attempting any repair.
Understanding a Spun Propeller
- A spun propeller loses efficiency and speed.
- It often happens after hitting an underwater object.
- Visual inspection may not always reveal the damage.
Checking for a Spun Propeller
