A flooded outboard motor can put a damper on your weekend fishing trip, or even leave you stranded out on the water. Fortunately, clearing out the excess fuel is usually fairly simple, although some malfunctioning boat parts can cause more extensive engine trouble later. You should understand why motors flood and how to get them started in order to keep this common problem from ruining your outing. Below, learn why motors flood and how you can help your boat in this situation. 

Why Do Motors Flood?

When the mixture of air and fuel inside the motor is off, fuel can fill the carburetor and foul the spark plugs, making it nearly impossible to start. Flooding is often caused by leaving the choke engaged too long, but it can also be related to low compression in one of the cylinders. Problems with the sensors and other boat parts can also cause your outboard motor to flood.

How Can You Fix the Issue?

If your motor won’t start and you notice a strong fuel odor, just move the throttle to the wide-open position and crank the engine without engaging the choke. This opens the carburetor plates, allowing air to move freely through the engine and clearing out the excess fuel.

The process for fuel-injected motors is very similar. Putting the boat into neutral, opening the throttle, and cranking the motor lets the electronic controls know that the engine is flooded. The system will respond by going into clear-flood mode, which holds back the fuel. You may need to try several times, but this process can usually get a flooded motor started.
