Yamaha Impeller - Cooling System Component - 67F-44352-00-00

Overview

If there’s one part I never gamble with on a Yamaha, it’s the impeller. Once it starts to wear down, you’ll see it in water pressure and engine temps pretty quick. I’ve pulled plenty of old ones that looked fine at a glance but weren’t moving enough water anymore. A fresh impeller keeps the cooling system doing its job so you can run without worrying about overheating.

Key Features

• Consistent Water Flow – Keeps cooling water moving efficiently through the engine.
• Genuine Yamaha Fitment – Designed to match factory pump housing and components precisely.
• Supports Engine Cooling – Helps maintain stable operating temperatures under all conditions.
• Flexible Rubber Design – Built to maintain shape and performance under continuous use.
• Reliable Performance at All Speeds – Provides steady water flow from idle to full throttle.

Engine & Boat Compatibility

Compatible with select Yamaha outboards using this impeller. Verify fitment based on your specific engine model.
