This Polastorm SEMA aluminum propeller for Suzuki 150–300 hp is a 3-blade propeller with a 16" diameter, 17" pitch, and 15 splines. The variant is intended for Suzuki 4-stroke outboard motors within the specified power range.
The propeller is manufactured from aluminum and belongs to the SEMA series. The combination of 16" propeller diameter and 17" pitch identifies the specific variant, while the hub is designed for a propeller shaft with 15 splines.
Compatibility includes Suzuki 4-stroke motors of 150–300 hp with a 4 3/4" gearcase. The gearcase measurement is a compatibility metric for the motor's lower unit and should not be confused with the propeller diameter.
A WaterGrip hub kit, part no. 52.456.90, can be purchased separately if the installation requires it. It is documented as a related accessory but is not listed as mandatory for all installations.
When selecting a propeller, the diameter, pitch, number of splines, engine power range, and gearcase size must match the current engine installation.
Always check the engine model, gearcase, propeller shaft, and existing propeller specifications before purchase.
