The PROP GUARD - For Your Outboards & Stern Drives

In tests, vessels with Prop Guard® installed were put through tight figure 8 turns. The handling characteristics were greatly improved, as greater lateral area of the nozzle produces a larger effective rudder area. There is significantly greater steering control at high speeds, when the vessel made 360 degree turns in 30 to 40 feet compared to 60 to 80 feet with an unguarded propeller. The stopping ability of the boat is also dramatically increased as the nozzle presents a greater blockage area

Prop Guard® allows a vessel with a planing or displacement hull to be trimmed so efficiently that porpoising or pounding of the hull can be greatly reduced. The fact of less pounding on the hull should reduce hull stress. When a boat is porpoising, sometimes the upper portion of the propeller will be in and out of the water allowing the engine to rev and release. The improved handling can also help reduce this type of engine stress.

There are no “minor” propeller accidents. Installation of the Prop Guard® on all propellers would greatly reduce prop blade injuries to humans and marine life. The added thrust also allows for better handling control of the vessel. The Coast Guard, life guards and military vessels are preparing to order Prop Guards® because of the greater propeller safety factor and increased vessel control that they can achieve.
