Yamaha - Tube, Water - Cooling System Component - 682-44361-01-00

Overview

The water tube is one of those parts that quietly keeps your Yamaha running at the right temperature. It carries cooling water from the lower unit up into the powerhead, and if it’s off even slightly, you’ll start seeing issues. I’ve dealt with engines overheating just because the tube wasn’t seated right or had corrosion buildup. When everything lines up properly, water flow stays steady and the engine runs the way it should.

Key Features

• Direct Cooling Water Transfer – Moves water efficiently from the lower unit to the engine.
• Genuine Yamaha Fitment – Matches factory routing and connection points for proper alignment.
• Supports Engine Cooling – Helps maintain consistent water flow to regulate temperature.
• Alignment Stability – Ensures correct positioning within the cooling system during operation.
• Durable Marine Construction – Built to handle water exposure, vibration, and heat cycles.

Engine & Boat Compatibility

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