Propeller protection device

Protect your drive train and propeller with the best rope, line and debris cutter there is. Available for both power and sail.

The SHAFT SHARK is a serrated edge circular blade machined from high quality (316L) type stainless steel. It is easy to install; no drilling, tapping or dismantling. It is available as a split 2x piece unit for quick and simple installation, no need to remove propeller. Also available as a single piece unit for larger diameter shafts.

Zero maintenance since there are no moving parts (cutters/bearings/zincs/stops) to maintain or replace annually. Easily re-sharpened if necessary.

What does it do?

Attached to your shaft just forward of your propeller, it rotates with the shaft, cutting away any rope, weed or debris that might try to entangle your shaft and propeller while you are underway.

Why do I need one?

  • To keep your propeller free from rope, weeds and underwater debris.
  • Eliminate the possibility of damage to your shaft, propeller and strut.
  • Eliminate the need for being towed due to fouled stern gear or propeller.

Drag and Efficiency

The SHAFT SHARK is sized to both the shaft diameter and the propeller hub diameter to ensure the lowest drag and minimal waterflow factors for the boat and propeller efficiency. Overall these two factors will vary depending upon the speed of the boat. This is why there are different model units to suit all shaft and hub combinations.
