It is the next step in the progression of our popular larger diameter VO series, the New Express Mach3 OS Series of Stainless Steel Propellers. The cup, leading and trailing edges, and blade geometry that are Turning Point characteristics were all improved by our Engineers and Propeller Experts. These modifications have produced a propeller with an excellent hole shot, impressive bow lift, and class-leading cornering. The chromium concentration of the New Express Mach3 is 20% higher than the competition, resulting in enhanced shine and corrosion resistance. Almost two-thirds stronger and five times more durable than standard stainless steel. Turning Point's Engineers and Designers can use this new material to create creative new designs that will help you get the most performance out of your boat.

Key Features:

• Large horsepower bay boats, offshore center consoles, and high horsepower pontoons/tritoon are all ideal candidates.
• It provides excellent mid-range fuel economy.
• It's a new casting method, high-quality materials, increased corrosion resistance, and a higher gloss.

How Does Turning Point Design Industry Leading Performance Props?
When Turning Point designs a new prop for a given category, they identify the best performing OEM and Aftermarket stainless steel props in the market that fits into that category. A better aluminum & stainless steel version is designed at the same time using the same geometry & drawing. Through testing, Turning Point’s engineers modify the design until it performs better than the best competitive Stainless Steel prop.

Why upgrade to a Tuning Point stainless steel propeller?

- Stainless steel propellers are much more durable compared to aluminum.

- Substantial better performance over competitive aluminum propellers. (Minimal performance difference, around 0.5-1mph speed gain over Turning Point Aluminum Propeller Designs.)

- Expect better performance over competitive OEM and Aftermarket Stainless Steel propellers.

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 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.

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.

Large Free Flowing Exhaust Ports:

Turning Point's Propeller Housings have massive Exhaust flow pathways. Their Propellers have 40% more exhaust flow Area versus competive product. More exhaust flow and less backpressure can generate more horsepower. Like headers for your boat.
