This Polastorm SEMA aluminum propeller for Johnson/Evinrude and Selva is a 3-blade fixed-pitch propeller for outboard motors. This variant has a diameter of 10 1/4", a pitch of 13", and 14 splines.
The propeller is manufactured from aluminum and features right-hand rotation (RH). It is designed for a 14-spline propeller shaft and a 3" gearcase. The pressed-in rubber hub is integrated into the propeller.
The size specification 10 1/4 x 13 describes the propeller's diameter and pitch. The combination of diameter, pitch, rotation, number of splines, and gearcase size must match the engine drive and the existing propeller.
