Overview

The Yamaha 6AW-W0078-00-00 Water Pump Repair Kit is an OEM maintenance solution designed for Yamaha F300 and F350 V8 outboard motors. The water pump is one of the most critical components in any outboard engine, responsible for circulating cooling water through the powerhead to prevent overheating. Over time, impellers wear down and seals degrade, making periodic water pump service essential for engine longevity and reliable on-water performance. This kit provides the parts needed to restore the water pump to proper working condition.

As a genuine Yamaha part, this repair kit is engineered to match the exact specifications of the F300 and F350 V8 outboards, eliminating the fitment concerns that can arise with aftermarket alternatives. Using OEM components for cooling system maintenance is especially important given the high horsepower output of these engines, where adequate cooling directly affects performance and engine life. Whether you are performing routine preventative maintenance or addressing a cooling issue, this kit offers a factory-backed solution for keeping your Yamaha V8 outboard operating at its best.
