This Polastorm SEMA aluminum propeller with 13 splines is a 3-blade, right-hand rotation propeller for select Suzuki outboard motors as well as compatible Suzuki-based Johnson/Evinrude 4-stroke engines. The propeller has a nominal size of 11 1/2 x 10″ and is designed for a 3 1/4″ gearcase.
Size is indicated as diameter x pitch. The diameter of 11 1/2″ nominally corresponds to 292.1 mm, while the 10″ pitch corresponds to 254 mm of theoretical forward movement per revolution without slip. The choice of pitch must be adapted to the boat's load, engine setup, and desired RPM.
The propeller is made of aluminum and features three blades along with a pressed-in rubber hub. The right-hand rotation design, also referred to as RH or regular rotation, is made for a propeller shaft with 13 splines.
For Suzuki, the documented power group includes 40, 50, 55, 60, and 65 hp 2-stroke as well as 40, 50, and 60 hp 4-stroke models. Relevant engine families include DT35C, DT40, DF40/DF40A, DT50/DT50M, DF50/DF50A, DT55, DT60, DF60A, and DT65, provided the gearcase and propeller shaft match the specifications.
The propeller is also linked to Suzuki-based Johnson/Evinrude 4-stroke engines of 40-50 hp, typically from model years 2000-2007, with a 3 1/4″ gearcase and 13-spline propeller shaft. It replaces Suzuki OEM reference 58100-88L10-019.
Power class alone is not sufficient when selecting a propeller. Check the gearcase, spline count, direction of rotation, clearance, and the original propeller's diameter, pitch, and OEM number before ordering.
