The Express Mach3 Series 14.3-inch D x 17-inch P LH Rotation (31501722) is a Turning Point 3-Blade Stainless Steel Thru Hub Exhaust Propeller suitable for 175 hp Yamaha applications. It is made of industry-leading TP17 stainless steel and is perfect for watersports, sterndrive boats, tri-toons, bay boats, and any other vessel with a stern lift. The Express series is ideal for applications requiring increased acceleration, cornering, and weight carrying capacity and is the best update of previous stainless designs from the 1970s, 1980s, 1990s, and 2000s, outrunning most modern props, including five-blade ski props.

Key Features:

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.

Turning Point has built their reputation on a relentless focus on engineering the best performing aluminum propellers in the World. Utilizing state-of-the-art Squeeze Casting technology, they produce Hustler 3 Blade Propellers that run as fast as their competitors' Stainless Steel Props, and even sometimes faster! Super stiff metallurgy, unique blade geometry, aggressive pitch, rake, and cup all give you the best they can offer! Not only does top speed, handling and hole shot improve, but also mid-range performance, which will save you a ton in gas usage. If you want the most your boat and engine combination can offer, then the Hustler 3 Blade delivers.

Utilizing almost 40 years of race boat and high performance prop design expertise, our Express Mach3 series of props captures all the best techniques and technologies available to get the most out of your boat. Aggressive pitch angles, radical designs, sharp cup profiles. These three blade propellers excel at achieving maximum speed, while delivering Best-in-Class handling and acceleration. Hole Shot? Got it, and hang on! Cornering? We've got that, too! Top Speed? We say "No Faster Prop on the Water" for a reason!

Upgrading your current propeller from aluminum to stainless steel, or from an old generation design to the latest technology, Express Mach3 Propeller is the best investment in boat improvement you can make. Today's New Designs will run circles around the competition, and can make dramatic improvements in boat performance. The gain in fuel economy can often pay for the cost of a new propeller in one or two seasons, making it a sound investment in your time on the water.
