Express® Mach3™ OS™ - Left Hand - Stainless Steel Propeller - OS-1621-L - 3-Blade - 15.6" x 21 Pitch

The Express® Mach3™ OS™ Series of Stainless Steel Propellers are the next step in the evolution of our very popular larger diameter VO series. Our Engineers and Propeller Experts made improvements to the cup, leading and trailing edges, and the aggressive progressive rake and blade geometry that are Turning Point hallmarks. These modifications have produced a propeller with excellent hole shot, impressive bow lift, and class leading cornering. 

The Express Mach3 OS is perfectly matched to large horsepower bay boats, offshore center consoles, and high horsepower pontoons/tri-toons. It will fit all 90hp and larger 4.75" gearcase outboards from all engine manufacturers, and Mercury® Alpha One™ and Bravo One™, and Volvo® Penta® SX sterndrives. Large diameter three blade propellers offer great mid-range fuel economy in many applications. Whether you are looking to maximize your time on the water, extend your cruise range, or just stretch your fuel dollars, the Express Mach3 OS is a great choice to get the most out of your boat.

Just used and had to apply a second coat And still some sun bleached spots still bless through ! I don’t recommend ! P.S. my vehicle is only five years old ! So it’s not like it’s been sun bleached for ten or fifteen years But having said that , For the rubber gaskets around the windows and inside track on the bottom that is black as well And gets dirty all the time , this product works great !
