The outboard Engine is the heart of your boat, providing you with all the power you need to explore and navigate across the seas. To keep it running smoothly, consistent and proper maintenance is essential–starting with flushing your engine after sailing in saltwater. In this article, we’ll discuss the importance of flushing your outboard motor, what tools and techniques you need, and provide guidelines on how to do it right for optimal performance.

The Importance of Flushing Outboard Engines 

Flushing your Outboard Engine is no longer a question of ‘if’, but ‘when’. It’s a simple process that can prevent costly repairs and ensure the longevity of your engine. Here are some compelling reasons to get flushing:

The Foaming Fury of Saltwater

Outboard motors valiantly battle the constant onslaught of saltwater, risking corrosion and damage to their vital components. A simple freshwater flush can guard against this peril, washing away any salty residue from the cooling passages.

Deflect Debris and Sand

Run your engine in shallow water or near sandbars, and you risk a powerful foe–sand and debris–entering the cooling system. A flush can break up any blockages, restore water flow, and keep your engine running cool.

Supercharge Performance and Longevity

To take full advantage of your outboard motor’s capabilities, regular flushing is essential, preventing buildup of salts and debris that lead to starts that are slow and listless. By removing harmful substances, you also preserve its lifespan, allowing it to be enjoyed for years to come.
