Shark is a serrated edged disc, machined from high quality type
316 stainless steel. The internal diameter is machined to
fit the shaft diameter of your boat either metric or standard.
Attached to your shaft, it
rotates with the shaft, cutting anything that might become
entangled around the shaft or propeller. By cutting
through lines, nets or other underwater debris as soon as it
catches, the Shaft Shark reduces potential damage to your drive
train, shaft and prop.
