This Polastorm SEMA aluminum propeller is a 3-blade aftermarket propeller for Suzuki 150–300 hp, 4-stroke outboard motors. This variant has a diameter of 16″, a pitch of 20″, and LH (left-hand) rotation.
The propeller is designed for a 4¾″ gearcase and a propeller shaft with 15 splines. The LH rotation makes it suitable for engine and installation configurations where a left-hand or counter-rotating propeller is required. Always check rotation direction, diameter, pitch, gearcase, and number of splines before ordering.
The 3-blade design is manufactured from aluminum. Polastorm aluminum propellers are based on a heat-treated, A356-based titanium-aluminum hybrid alloy and are produced using APC precision casting. The surface is corrosion-protected with robotically applied powder coating.
The manufacturer's part number is 5288-3160-20. The corresponding right-hand RH variant with the same diameter and pitch has part no. 52.456.08 and manufacturer number 5287-3160-20.
WaterGrip with part no. 52.456.90 is documented as a separate accessory for Suzuki 150–300 hp with 4¾″ gearcase. The relevant mounting group is Polastorm Group E/SEMA, and the manufacturer's hub kit reference is F28. Mounting parts are not necessarily included and must be selected according to the specific installation.
Always check engine model, gearcase, propeller shaft, rotation direction, and existing propeller data before purchasing.
