9 1/4" x 9" Stainless PolaStorm Propeller: Suzuki 8-20hp OB's


A high-quality propeller makes a huge difference in how your boat feels & performs. PolaStorm propellers have an enviable reputation around the world and we are proud to be the sole distributer for UK & Ireland. Direct purchase from the manufacturer allows us to offer you excellent value for money.

This SEMA Series propeller features stainless steel construction, which reduces blade flex and ensures more grip, and lower planing /  cruising speeds. It has a spiral flute hub design, to create freer flowing exhaust, helping to prevent loss of performance. PolaStorm R&D Team specifies ASTM A890-4A duplex stainless steel. This is heat treated to create a tensile strength of up to 750 Mpa with enhanced anti corrosion properties.

Please Note: if you are upgrading from a 3 blade aluminium propeller, this propeller would suit if you currently have a 10" or 11" pitch, which can operate at the correct manufacturers max RPM.
