Polastorm propeller material R&D technical team uses ASTM A890-4A duplex stainless steel formulation, followed by heat treatment to create tensile strength of up to 750 Mpa and extreme anti-corrosion.
Polastorm stainless steel propellers all utilize spiral flute exhaust design and the marine industries greatest Interchangeable Hub System with Gearcase Noise Reduction System (GNRS). The best proven designs have been chosen to match specific engines horsepower groups with a wide range of propeller pitch choices.
This Group E (Suzuki) is suitable for:
- DT150-225 hp (2 stroke), 1986-present
