The Cutter's blades attach to the propeller shaft and cut away dangerous obstructions while the shaft turns.
A fixed blade is mounted in bearings integral with the rotating cutter creating a powerful shearing action as the blades pass each other. A striker plate mounted on the stern gear (strut) locks the fixed cutter, while also allowing the shaft both axial and radial movement.
The simple, trouble free mechanism absorbs all vibrations, noises or rumblings and there is never any wear on the shaft.
The needle sharp teeth extend to the very tips of the blades for maximum cutting power.
Installation is straight forward and does not require removal of the propeller.
To determine the correct Cutter model for your boat please refer to the drawing and table below. If you have insufficient clearance between the propeller and the strut, we can provide spacers that will extend the prop shaft aft by the required amount.

For maximum efficiency, select the Cutter model with the same number of blades as your propeller.
Alternatively, a two blade cutter may be used on a two or four blade propeller, and a three blade cutter may be used on a three or five blade propeller.
