Yamaha - Water Tube - Cooling System - 61N-44362-10-00

Overview

The water tube is one of those parts you don’t think about until cooling issues show up. It plays a key role in moving water from the lower unit up into the powerhead, and if it’s damaged or out of place, your engine won’t stay cool for long. This is the kind of component I always check when doing lower unit work or chasing overheating problems. A solid, properly fitted tube keeps everything flowing the way it should.

Key Features

• Direct Cooling Flow Path – Channels water efficiently from the pump to the engine for proper cooling.
• Corrosion-Resistant Build – Designed to handle constant exposure to moisture and saltwater conditions.
• Precision Fitment – Matches factory dimensions for proper alignment during installation.
• Durable Construction – Built to withstand vibration and long-term marine use.
• Essential Cooling Component – Supports consistent engine temperature by maintaining steady water flow.

Engine & Boat Compatibility

Compatible with Yamaha outboard engines that use a standard internal water tube cooling system. Commonly found in small to mid-range horsepower outboards used on fishing boats, skiffs, and utility vessels. Always verify fitment with your specific engine model.
