Why does my outboard motor keeps flooding?
A flooded engine has too much gas in the system, and not enough of it is atomizing to combust. It usually results from repeated starting attempts with the choke or primer out. The cure to getting a flooded motor to start is to close the choke and open the throttle to half or more while starting the engine.
How do you Unflood an outboard motor?
To restart when flooded, open the throttle all the way (with no choke), to admit as much air as possible, and crank the motor until the excess fuel is expelled. If the plugs are soaking wet, you can dry them first (with compressed air, or laid out in the hot sun), to aid starting.
How can I prevent my engine from flooding?
If you’re only moving your car a short distance, it’s best to leave the engine running for a few minutes to bring the car closer to its normal operating temperature and to use up the fuel left in the combustion chamber, preventing the risk of flooding.
Will a flooded engine fix itself?
