Description

Shaft Shark Model SS300 – Protect your drive train and propeller with the best rope, line and debris cutter there is.

The SHAFT SHARK is a serrated edge circular blade machined from high quality 316L type stainless steel. It attaches to your shaft just forward of the propeller and rotates with the shaft or saildrive hub, cutting away any rope, weed or debris that might try to entangle your shaft & propeller. It is a two-piece, split unit and may be installed on both shafts and saildrive systems.

  • Keep your propeller free from rope, weeds and underwater debris
  • Eliminate the possibility of damage to your propeller, strut and cutlass
  • Eliminate the need for being towed due to fouled stern gear or propeller
Choosing the right model

Installation

The SHAFT SHARK requires minimal clearance between the cutlass bearing and the propeller hub.  It is installed with the cutting blade side facing forward and flush up against the propeller hub face.  It is not required to remove the propeller for installation. The Shaft Shark is kept securely in place by the clamp action of two allen-head bolts using Vibra-Tite VC-3 or Loctite on the screws/bolts.

See complete instructions here before installing your Shaft Shark.

Drag
The SHAFT SHARK is sized to both the shaft diameter and the propeller hub diameter to ensure the lowest drag factor for the boat. Overall drag will vary depending upon the speed of the boat … the propeller hub diameter and the size of the SHAFT SHARK installed. This is why there are different model units to suit the shaft and hub combinations.
Maintenance
With no moving parts maintenance is minimal. There are no moving parts to maintain or replace on an annual basis. The edges can be re-sharpened when necessary. Do NOT use a wire brush or like to clean the shaft shark as it may compromise the outer surface area.
