TEMPEST PLUS 21P RH 8M0151382
Fine tuned.
Enhanced Performance Vent System (PVS®) enables boaters to optimize forward and reverse thrust for greater control with Joystick Piloting for Outboards (JPO).
Just by varying the size of the exhaust hole and controlling your engine’s rpm, you can eliminate sluggish performance or compensate for changes in load in altitude. It’s technology that you can only get from Mercury.
Stainless Steel 15-5: Superior Corrosion Protection for Long-Lasting Dependability
A proprietary blend of 15-5 stainless steel perfectly balances strength and corrosion resistance in both freshwater and saltwater applications. Developed specifically for Mercury propellers.
Producing world-class Mercury propellers is no simple task
Producing a world-renowned Mercury Marine prop takes time and skill, not to mention advanced engineering and know-how. Every operation - from inception to completion - is centralized at Mercury's propeller manufacturing facility in Fond du Lac, Wisconsin.
Flo-Torq SSR
The Flo-Torq SSR utilizes Mercury’s proven Soft-Shift Rubber technology in a quiet hub kit that provides an NVH upgrade for Flo-Torq II hub applications where the maximum reduction of noise, vibration, and harshness is desired.
