This propeller cotter pin for Johnson/Evinrude is a replacement part for securing the propeller nut on the propeller shaft. The variant measures 4 x 25 mm and is designed for Johnson/Evinrude outboard motors of 50–140 hp.
The cotter pin is inserted through the propeller nut and the propeller shaft and bent after installation. This mechanically secures the propeller nut so that it cannot loosen during operation. The installation point is at the propeller nut and not at the propeller cone.
The spare part has the original number 314502, which also appears in the standardized number format 0314502. Documented aftermarket cross-references include Sierra 18-3742 and 18-3742-9, GLM 22120, as well as EMP 18-00578. The cross-references may be stated with other physical dimensions, and size as well as original number should therefore be checked before replacement.
