Express® Mach3™ OS™ - Right Hand - Stainless Steel Propeller - OS-1621 - 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.

Easy Claims Process
It is not a long complicated process to file and resolve a claim. Be warned--sometimes they will want you to send back the defective or damaged product, even if it's not worth the shipping ---they pay. Overall worth the investment though.

Asurion you made the return process simple
Working with Asurion was an easy process. My previously covered milk frother stopped working, and they fully refunded it with no questions asked. All I had to do was ship the broken item back to them and they sent me a gift card. To cover the initial cost, no questions asked. The refund process was a very simple and painless.
