Polastorm SEMA aluminum propeller for Suzuki 150–300 hp is a 3-blade outboard propeller for 4-stroke engines with a 15-spline propeller shaft and a 4¾" gearcase class. This variant has a diameter of 16", a pitch of 17", and counter-rotation, which is indicated by the L in the size designation 16 x 17L.
The propeller is made of aluminum and features SEMA geometry. The 16" diameter corresponds to 406.4 mm, while the 17" pitch corresponds to 431.8 mm. The counter-rotation makes this variant intended for installations where the engine's propeller shaft and rotation direction require a counter-rotating propeller.
Compatibility includes Suzuki 4-stroke engines in the 150–300 hp power range with 15 splines and 4¾" gearcase class. Engine power alone is not sufficient for selecting the correct propeller; the shaft connection, gearcase, rotation direction, diameter, and pitch must also match the existing installation.
A related WaterGrip component for 150–300 hp and 4¾" gearcase can be purchased separately under item no. 52.456.90, if the installation requires it.
Always check the engine type, gearcase, number of splines, rotation direction, and the existing propeller's dimensions before purchasing.
