Yamaha - Water Tube - Cooling System Delivery Component - 61A-44361-30-00

Overview

This is one of those parts that quietly does its job every second your engine is running. The water tube carries cooling water from the lower unit up into the powerhead, keeping temperatures in check. If it gets bent, clogged, or corroded, you’ll start seeing cooling issues pretty quickly. It’s a simple component, but when it’s in good shape, your entire cooling system works the way it’s supposed to.

Key Features

• Direct Water Transfer Path – Moves cooling water from the lower unit to the engine efficiently.

• Supports Stable Cooling Flow – Helps maintain consistent water circulation for proper temperature control.

• Corrosion-Resistant Construction – Built to withstand constant exposure to freshwater and saltwater environments.

• OEM Precision Fit – Designed to align correctly within the midsection for secure installation and proper sealing.

Engine & Boat Compatibility

Compatible with select Yamaha outboard engines. Always verify fitment using your engine model and specifications before installation.
