a little bit about

Prop Protector

The Prop Protector is a simple shaft driven rope cutter, rotating with the shaft and instantly cutting any rope, weed or debris picked up or snagged by the propeller.

Manufactured from high grade (316) Stainless Steel, the Prop Protector is easy to install – fully installed in minutes – with your boat out of the water or between tides. The clamp-on version can even be fitted by a diver if underwater installation is required. The Prop Protector sits on the shaft, between the propeller hub and the stern bearing, waiting to cut anything that threatens to entangle it. There are no moving parts to fail – just a razor sharp marine grade stainless steel blade – ready to slice through most marine debris.
