Yamaha - Water Tube - Cooling System Delivery - 69G-44361-20-00

Overview

Water flow is everything when it comes to keeping a Yamaha running cool, and this tube is right in the middle of that system. It carries water from the lower unit up into the powerhead, and if something’s off here, overheating isn’t far behind. I’ve seen engines run hot just from a damaged or misaligned tube after a water pump job. When it’s seated right and in good shape, you don’t have to think about it—and that’s exactly how it should be.

Key Features

• Efficient Water Transfer – Directs cooling water from the lower unit to the engine for proper temperature control.
• Precision Yamaha Fitment – Designed to align correctly with pump and powerhead connections.
• Corrosion-Resistant Construction – Built to handle constant water exposure in marine environments.
• Critical Cooling Support – Helps maintain consistent engine temperature under all operating conditions.

Engine & Boat Compatibility

Compatible with Yamaha outboard engines using standard water pump and cooling tube systems. Commonly used across a range of Yamaha motors on various boat types, from small utility boats to larger recreational setups.
