Part Number:
The New 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 maximise 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.

Proprietary Stainless Steel, TP17™
Formulated to meet the exacting requirements of the New Express Mach3 and Mach4 designs. 20% higher chromium content than the competition - more shine, better corrosion resistance. Almost 250% Stronger and 5X more durable than run-of-the-mill stainless steel. This new material allows Turning Point’s Engineers and Designers the freedom to produce radical new designs that will help you wring the most performance out of your boat.

MaxSpeed™ Dyno Balance ProcessesGives your boat a smoother running ride, higher top end speed, and increases fuel economy. This process is standard on every prop and is only offered as a costly option from other manufacturers. (Exclusive on all Mach3 and Mach4 Propellers)

Best “In-Class” Reversibility
Recent tests reveal that new Express Mach Series Propellers have up to 46% more reverse thrust over competitive propeller designs.

Tuned Vents for Fast Hole Shot
Turning Point uses this race boat proven technology to increase low speed acceleration and hole shot. Use it to get your boat on plane faster, and to your favorite fishing spot quicker! (selected models only 13” through 16” diameter 15+ Pitch).

Performance Tuned Rake Angles
Higher rake angles tighten the vortex produced by the propellers, adding to boat lift and overall performance.

High Flow-Through Barrel Exhaust System
Maximising exhaust flow increases horsepower and top end speed.

Tuned Progressive Pitch Angles
Accelerating and channeling water to minimize slip increases performance and fuel economy.
