EXPRESS MACH3 OS BOAT PROPELLER(SERIES OS) 15.6X19 3 BLADE STAINLESS STEEL LH (

The Turning Point Express Mach3 OS is a 3-blade stainless steel propeller with a 15.6-inch diameter and 19-inch pitch, designed for left-hand rotation. It is the next evolution in Turning Point's larger diameter VO series, featuring improvements to the cup, leading and trailing edges, and aggressive progressive rake and blade geometry. These modifications provide excellent hole shot, impressive bow lift, and class-leading cornering. The propeller is made from proprietary TP17 stainless steel, which has 20% more chromium than competitors, offering superior shine and corrosion resistance, and is significantly stronger and more durable than standard stainless steel. It also features large free-flowing exhaust ports, providing 40% more exhaust flow area compared to competitive products, which can lead to increased horsepower and top-end speed. The Mach3 OS is ideal for large horsepower bay boats, offshore center consoles, and high horsepower pontoons/tri-toons. It fits many 90 hp - 300 hp engines with a 4 3/4-inch gearcase, including outboards from various manufacturers (Evinrude, Force, Honda, Johnson, Mariner, Mercruiser, Mercury, Nissan, OMC, Parsun, Suzuki, Tohatsu, Volvo Penta, and Yamaha) and Mercury Alpha One and Bravo One, and Volvo Penta SX sterndrives. A brand/model-specific 500 or 700 series Turning Point MasterGuard hub kit is required for installation and is sold separately.
