0765350 Evinrude Johnson Impeller | Genuine OEM BRP Outboard Part

🔧 Product Description

Genuine BRP Evinrude Johnson Water Pump Impeller and O-Ring Assembly - Part Number: 0765350

A genuine BRP water-pump impeller and sealing O-ring assembly for selected Evinrude and Johnson 25 Jet, 35 Jet, 40HP, 48HP and 50HP two-stroke outboards.

The flexible impeller is driven by the vertical driveshaft inside the gearcase water pump. Its vanes draw cooling water through the lower-unit intakes and circulate it through the powerhead.

Part number 0765350 is commonly supplied as the impeller together with the matching pump O-ring rather than as a bare impeller only.
