Advanced TP17™ Stainless Steel

Our proprietary TP17™ stainless steel is formulated specifically for the Express Mach3 and Mach4 designs. With 20% higher chromium content than standard stainless steels, TP17™ offers:

• Enhanced shine and corrosion resistance
• Nearly 250% increased strength
• Five times the durability of typical stainless steel

This advanced material allows for radical new designs that deliver unmatched performance and longevity.

Optimized Exhaust Flow

Turning Point's propeller housings feature large, free-flowing exhaust ports, providing 40% more exhaust flow area compared to competitors. This increased flow reduces backpressure, potentially generating more horsepower and improving overall engine efficiency—akin to installing high-performance headers for your boat.
