Yamaha - Impeller - Cooling System - 6E0-44352-00-00

Overview

If there’s one part I never take chances on, it’s the impeller. This is what keeps water moving through the motor, and once it starts to wear or lose flexibility, cooling performance drops fast. I’ve seen perfectly good engines overheat just because an old impeller finally gave out. Replacing it on schedule is one of the easiest ways to avoid bigger problems out on the water.

Key Features

• Efficient Water Circulation – Pumps water consistently through the engine to maintain proper cooling.
• Flexible Rubber Vanes – Designed to flex and recover shape for reliable performance over time.
• Heat and Wear Resistant – Built to handle friction and temperature inside the water pump housing.
• Direct OEM Replacement – Matches original specifications for proper fit and dependable operation.

Engine & Boat Compatibility

Designed for Yamaha 2-stroke outboard engines using standard water pump systems. Commonly used on smaller horsepower motors found on skiffs, jon boats, and lightweight fishing setups.

FAQ

Q: How often should I replace my impeller?
A: Most boaters replace it every season or every 100 hours, depending on use.

Q: What are signs of a failing impeller?
A: Weak or no water flow from the telltale, overheating, or inconsistent cooling.

Q: Can an impeller fail suddenly?
A: Yes, especially if it’s old or has been run dry even briefly.

Q: Is this something I can replace myself?
A: If you’re comfortable dropping the lower unit, it’s a straightforward maintenance job.

Q: Does running in sandy or shallow water affect it?
A: Definitely—sand and debris can wear the vanes down much faster.
