🔧 Product Description

Genuine BRP Evinrude Johnson Pin-Key Water Pump Impeller - Part Numbers: 0777129 and 0389589

A genuine BRP flexible water-pump impeller for selected 40HP, 50HP, 55HP and 60HP Evinrude and Johnson two-stroke outboards.

This impeller uses a pin-style drive key. It must not be confused with later wedge-key impeller 0777214, even though both are used in similar horsepower ranges.
