Flush Outboards Frequently
Did you know that flushing is an essential component of proper outboard motor maintenance? In fact, you should be flushing after each use. This might seem excessive but when you take into account the fact that whenever you run your Yamaha outboard motor, the intake ports are exposed to salt and brackish water as well as sand, chemicals, minerals, grass particles, and more. You may not realize it but all of these can end up damaging your motor’s cooling system in the long run.
You might always be aware of the fact that saltwater is one of the most harmful elements as it leads to corrosion. Over time, this will result in decreased water flower and, if you let it go long enough without flushing, overheating will eventually occur. The good news is that you can avoid blockages and overheating by flushing your Yamaha outboard motor after each use.
So, how do you go about flushing Yamaha outboards? There are a few different methods you can choose from. Whether you choose to use the built-in flushing attachment, or flush muffs. While all of these methods will get the job done, there are some factors to consider when choosing how to go about it.
Flush Muff Method
This method starts the same as the previous one with the engine in a vertical position and in neutral for 15 minutes. Next, screw the hose into the flush muff connector and then place the flush muffs over the water inlets. Slowly turn on the water until you see some of it leaking out from around the flush muff rubber cup. Confirm the rubber cups are in place over the inlets.
Start the outboard and again set the throttle to no more than a fast idle of 800 to 900 RPM max. Keep your eye on the water coming out of the pilot tube at the lower rear of the cowling. If you need to, you can increase the water flow. You should notice water exiting the back of the gearcase. Run the engine for 15 minutes. Finish by stopping the engine and turning off the faucet.
Built-In Flushing Device
In this case, your engine can be tilted or vertical. You’ll find the built-in flushing device, which is a hose fitting, located near the lower rear cowling. Connect the hose to the flushing device fitting and turn on the faucet. Let the freshwater run through the motor for 15 minutes. When it’s complete, turn off the faucet and disconnect it. Place the cap back on the flush fitting as instructed in your owner’s manual.
