Why Flushing Your Outboard Engine Matters

After a day on the water—especially in saltwater—residue like salt, mud, and minerals can build up inside your outboard’s cooling passages. If left unchecked, this buildup leads to corrosion, overheating, and performance loss. Using a Yamaha-engineered flusher lets you flush your outboard engine easily, helping to clear internal lines and maintain consistent cooling.

Even if you store your boat out of the water, flushing is one of the simplest and most effective ways to extend your engine’s lifespan.
