This Polastorm SEMA aluminum propeller is a 3-blade propeller for 150–300 hp 4-stroke Suzuki outboard engines with a 4¾″ gearcase and a 15-spline propeller shaft.
The propeller has a diameter of 16″ and a pitch of 21½″. This corresponds to a propeller diameter of 406.4 mm and a theoretical advance of 546.1 mm per revolution. The combination of diameter and pitch must always be matched to the engine, gear ratio, boat type, load, and the recommended RPM range.
The 3-blade aluminum construction is manufactured using APC precision casting and hybrid casting with strontium, aluminum, and titanium. The surface is powder-coated with an anti-corrosion AkzoNobel coating.
The SEMA geometry is designed for the 150–300 hp 4-stroke Suzuki engine group. Compatibility requires a 4¾″ gearcase and a 15-spline propeller shaft. Always check the engine's gearcase, shaft, permitted propeller size, and existing propeller specifications before purchase.
The WaterGrip mounting product with item no. 52.456.90 is available as a separate accessory for this engine group and is purchased separately if the installation requires it.
