Also available as a single piece unit for larger shafts. Models are split units and so installation is simple and quick. No need to remove the propeller to install.

How do I choose the right model?
• Supply the shaft diameter on your boat either standard SAE (inch) or metric.
• Supply the diameter of the fwd end of your propeller hub.

What is a SHAFT SHARK?

The SHAFT SHARK is a serrated edge circular blade … machined from high quality (316L) type high corrosion resistant stainless steel. It is a split two-piece unit for quick and simple installation on shafts & Saildrive propeller hubs.

What does it do?

Attached to your shaft just forward of your propeller, it rotates with the shaft or Saildrive hub, cutting away any rope, weed or debris that might try to entangle your shaft & propeller.

Why do I need one?

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

How do I choose the right model?

Supply (1) the shaft diameter on your boat either standard SAE (inch) or metric and (2) the diameter of the forward end of your propeller hub. For saildrive units, supply the make and model of your propeller.

Installation

As all models are a split, two-piece unit, the installation is simple and quick. There is no need to remove the propeller. There is no need for drilling/tapping or shaft extension. We supply the locking glue. Installation can be done underwater.

The SHAFT SHARK Models 300-500 require 0.90” to 1.00” inch (23-25mm) of shaft clearance between the cutlass bearing and the propeller hub. Models 600 & above require 1.25" to 1.50" clearance. This allows for sufficient clearance with the cutlass bearing for shaft movement when maneuvering and for water-flow through the cutlass bearing.

Drag

The SHAFT SHARK is sized to both the shaft and the propeller or Saildrive 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. Therefore, there are different model units to suit the shaft and hub combinations.

Maintenance

With no moving parts to maintain or replace on an annual basis maintenance is minimal. The edges can be re-sharpened with a fine file of stone.
