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

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.

Note: A Hub Kit is required for installation of this propeller. See the Turning Point Selection Chart or the Prop Wizard™ for hub kit selection.

Comfortable, Hypoallergenic, and Great Value
Size: King (Pack of 2), Style: Soft, Configuration: Pillow
These pillows are a solid upgrade for everyday sleep. They’re soft but still provide enough support for both back and stomach sleeping, and the down-alternative fill is perfect if you’re sensitive to allergens. The microfiber cover feels smooth and well-made, and they fluff up nicely after decompressing. Overall, a comfortable and affordable set that gets the job done.

Best for decorating. Not sleeping.
Size: King (Pack of 2), Style: Soft, Configuration: Pillow
These are perfect as inserts for decorative shams and the price was great. I don't think that I would ever want to use them for sleeping. They seem slightly lumpy and don't look they would last for very long with constant use.

Really impressed with these pillows for the price. They’re soft but still provide decent support, and work well for both back and side sleeping. No weird smell and very comfortable overall. Definitely a great budget option! 👍
