Back to Basics: The Importance of Flushing
This tech tip, from our Customer Relations team, is a “Back to Basics” reminder of how important it is to flush your outboard motor after each use.
Flushing the Motor with the Built-In Flushing Attachment
Do not perform this procedure while the engine is running. The water pump may be damaged and severe damage from overheating can result.
1. If the boat is remaining in the water during flushing, tilt the outboard motor up until it is completely out of
the water. This will allow the fresh water to flush out the water and exhaust passages in the midsection
and lower unit that would otherwise remain below the water level.*
2. Disconnect the freshwater flush adapter hose from the fitting on the bottom cowl.
3. Connect the freshwater flush adapter hose to the garden hose.
4. With the engine off, turn on the water supply and let the water flush through the cooling passages for about
10 to 15 minutes.
5. Turn off the water supply and disconnect the freshwater flush adapter hose from the garden hose. Reattach
the freshwater flush adapter hose to the fitting on the bottom cowl and tighten it securely.
If the freshwater flush adapter hose is not properly reconnected to the fitting on the lower
cowling after flushing, cooling water can leak out of the flushing hose and the engine can overheat,
causing severe damage.
It is best to perform this maintenance procedure after each use. Built-up debris and deposits will stay in the
motor if it’s not properly flushed out and can damage the unit.
Remember, you can always refer to the “Maintenance” section in their outboard’s owner’s manual for this procedure and more in-depth information. Additionally, you can watch our “Fresh Water Flushing–Maintenance Matters” service video by scanning the QR Code below.
