This Polastorm SEMA aluminum propeller with 14 splines is a 3-blade, right-hand rotation propeller for select Johnson, Evinrude, and Selva outboard motors. The variant has a diameter of 10 1/4″, a pitch of 12″, and is intended for a 14-spline propeller shaft in a compatible 3″ gearcase.
The propeller is made of aluminum and has a fixed, pressed-in rubber hub. Polastorm's aluminum propellers are produced using APC precision casting in a hybrid material based on strontium, aluminum, and titanium. The robotically applied AkzoNobel powder coating protects the surface against corrosion. For the aluminum propeller line, the stated material properties are 280 MPa tensile strength, 220 MPa yield strength, 9% elongation at break, and 89 HB hardness.
The right-hand rotation propeller is mounted directly onto a compatible 14-spline propeller shaft. The fixed rubber hub means the propeller does not use a separate replaceable Polaflex hub. Propeller selection should be based on the engine, gearcase, load, desired RPM, and the required pitch.
Compatible engine models
For Johnson and Evinrude, documented compatibility includes the 15 HP E-TEC H.O. from 2011, 20 HP 2-cylinder from 1984-1997, 25 HP Commercial from 1993-2005, 25 HP 2- and 3-cylinder from 1984, 25 HP E-TEC from 2009, 30 HP 2-cylinder from 1984, 30 HP E-TEC from 2009, 35 HP 2-cylinder from 1979-1983, and 35 HP 3-cylinder from 1997-2002. For the 2002 model year of the 35 HP 3-cylinder, compatibility must be checked particularly carefully.
For Selva, the propeller is specified for 20, 25, 30, and 45 HP 2-stroke engines with a 3″ gearcase and 14 splines.
OEM and cross-references
The propeller has OEM cross-reference 765050 for BRP, Evinrude, Johnson, and OMC. The Polastorm part number is 2267-3103-12. Documented aftermarket cross-references are Solas 2211-103-12, EMP P2211-1025-12, and Turning Point 21201310. The product is an aftermarket propeller and not an original BRP, Evinrude, Johnson, or Selva spare part.
Alternative SEMA variants in the same family are available with 11″ and 13″ pitch. These are alternative propeller choices and not direct replacements without checking the engine's recommended RPM range and the boat's load.
Always check engine/drive model, model year, gearcase, number of splines, rotation direction, desired pitch, and original part number before purchase.
