Preventative Outboard Motor Care: Part Four

If you find the water used to flush your engine is hot or has debris in it, the most common culprit is some grime stuck in the flow tube. Insert a small piece of wire into the flow tube to dislodge whatever is blocking the system. If this doesn’t work, more often than not it’s a serious problem with the water pump, and you’ll have to take the boat to your mechanic. Once you’ve successfully flushed the engine, it’s time to move on to the other systems.

Disconnect the fuel line so the engine has an opportunity to burn all of the gas and outboard motor oil in the carburetor. A quick caveat: Always use fresh fuel in your vessel, so if the gas has been sitting around for more than two months, get rid of it. In addition to burning the excess fuel in the carb, also be sure to check the fuel line for cracks and signs of wear. In our final installment tomorrow, we will finish checking the fuel systems and cover a few more steps you can take to preserve your boat.
