Shaft Shark Saildrive Model – 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 available as a two-piece / split unit and a single-piece unit. It 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
Installation
Installation is simple and quick. No need to remove the propeller to install. Installation underwater by a diver? … Yes, simple & easy. Included with each unit is 1.0ml of Vibra-tite VC3, which is a Loctite type material and is also suitable for underwater installations.
Models #900 & #1200 are single piece units that will require removal of the propeller to install.
The SHAFT SHARK requires less than 0.90 inch (23mm) of shaft clearance between the cutlass bearing and the propeller hub. Models #600 & above require 1.25~1.50 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 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.
