The R&D technical team at Polastorm uses ASTM A890-4A duplex stainless steel construction, followed by heat treatment, to produce propeller materials with extreme anti-corrosion and tensile strengths of up to 750 Mpa. All Polastorm stainless steel propellers include a spiral flute exhaust design and the best Interchangeable Hub System with Gearcase Noise Reduction System available in the marine industry (GNRS). The best-tested models have been selected to match specific engine horsepower groups with a range of propeller pitch options.
Key Features:
-
The prop is made of stainless steel that gets stronger and tougher over time.
-
Higher rake angles increase boat lift and overall performance by tightening the propeller vortex.
-
The handling and boat lift is increased by aggressive rake and cupping.
-
Progressive pitch angles that have been tuned accelerate and channel water to reduce slide, improve performance, and maximize fuel efficiency.
