1) Greater thrust
2) Higher cruising at minimum motor RPM RESULTING IN FUEL SAVINGS.
3) Significant directional steering control.
4) Outstanding boat leveling trim control.
5) Complete Propeller protection. (Water Skier safety)
6) Significant reduction of Propeller wake (Preventing wake nuisance for boats nearby and preventing wake damage to river and channel banks)
7) The vortex vanes between the outer and inner guard nozzle create a similar effect as counter rotating propeller arrangements, canceling the torque reaction, and the Propeller vortex of a single Propeller installation (Simple application for submarines and torpedos)
 
Once fitted this propeller guard will protect you from major injury or death with coming into contact with a moving propeller. This guard is a must around small children, beginner boat drivers or any boat that could be around people swimming in the water.
What is a Propeller Guard?
The Propeller Guard is a two piece plastic injection molded cage with no moving parts, no electrical wiring, and no hydraulic hoses that will completely cover the propeller. The Propeller Guard is attached by a specially designed clamp system and bolts. The Propeller Guard’s two halves are attached like a clam shell to the cavitation plate and the skeg of any outboard motor. The easy installation can be accomplished by anyone with simple tools in about 20 minutes.
