🔌 Function

Replaces the shaft and bearings of the seawater pump so the impeller runs true and the shaft seal runs on an unworn surface.

⚠️ Common Signs of Failure

• Rumble or squeal from the pump with the engine running
• Shaft or impeller loose to the hand with the cover off
• Salt crust or seawater weep at the shaft
• Bearings found rough or corroded and the shaft grooved at the seal track
• Drive pin sheared so the impeller no longer turns with the shaft

🛠️ Service Notes

• Wear and seal package 21951400 also supersedes 875759 and covers the stationary faces of these pumps - order that when the wear plate and seals are the problem
• Renew the shaft seal and impeller with the kit and check the body bore for scoring
