- In this video we discuss why motors flood, we will disassemble a Mercury 6HP outboard carburetor and review what can cause flooding. Finally we will intentionally flood a motor and walk through how you can quickly unflood and start a flooded motor.
Safety First!
Never start your motor unless it’s in neutral!
Gas is flammable and dangerous, if gas is present kill the motor and all eliminate all heat and spark sources.
Always have a fire extinguisher on your boat.
Always take your motor to a trained mechanic if you don’t understand all the risks and are not trained to do repairs. Motor repairs and flooding can be dangerous.
Starting a flooded motor should only happen if it’s an emergency, it’s best to just let the motor sit and either dry out or just get a tow and take it to a mechanic.
Read your manual!
Here is a video where I did every maintenance item for this Mercury 6HP 4 stroke:: • EVERY MAINTENANCE ITEM...

WARNING** flooded motors have burnt up cars and boats. They can be dangerous. If gas overflows and hits a hot exhaust it can catch on fire! If you ever see gas dripping or overflowing in your motor, if it is safe to do so kill your motor, close your fuel valve, make sure all heat sources are away from your motor, and assess your situation. You are responsible to assess and safely react to your own situation. Never try to restart a motor that is dripping or overflowing with gas. It is dangerous. These starting procedure are only for minor flooding caused by the motor being flooded due to starting user error or if you need to start it in an emergency. If you have a mechanical issue causing your flooding, DO NOT TRY TO START THE MOTOR. Get to a safe place, assess the situation, and get a trained mechanic to fix the mechanical issue before restarting.

Sorry to be a downer but there is an easier way to get it running without all of that effort. I am a clammer in Massachusetts and go year round clamming. Even in 10 degrees. I have used a mercury 20 hp 2 and a 4 stroke for 21 years. To prevent flooding, don’t pump the ball ever. If flooded, pull the gas line off and pull the cord and clear the gas. Pull until it fires up then attach the gas hose back on. Simple fix and it has worked on at least a dozen of my friends motors as well.
Just wanna let you know I’ve been sitting in the middle of the lake for an hour. This video saved my life. Thank you kind sir.
Thanks for this excellent video. One part of it confuses me. You say the the key part of starting a flooded motor is to "maximize air flow and minimize gas going into your motor". But then you recommend a starting procedure that involves no choke and 100% throttle. Seems contradictory. Doesn't 100% throttle deliver the most gas possible into the engine? What am I missing here? I have a new (3.5 hours into the broken period) Yamaha 8HP outboard. Runs perfectly when I can get it started, but seems to flood far too easily, and then doesn't start at all until I drain the gas out of the cup and dry out the plugs. Very annoying, to be diplomatic. Advice PLEASE!!!
Yamaha motors will not let you maximize throttle unless it is in gear. If in gear you cannot pull the rewind.
choke while running will flood it good..putting in gear on bigger motor will enable use of full throttle to crank and give min gas and max airmotor sucks harder when throttle plate blocks air flow.. just like you use full throttle to un flood an old carbureted car..nice vid tho...
Overflow tubes simply rerouting too much gas out of your carb, i don't see an issue there, it happens when you prime too much gas thru external pump, its a safety mechanism, happened to me multiple times, had no issues starting or running motor
Mate cheers the help, engine hadn’t been run for months , engine was flooded, did no choke full throttled and the engine turned over first pull. Absolutely unreal 🤙🏾
So relieved to find this video. Too bad I found it after absolutely obliterating my shoulder trying to start my outboard for the first time, yesterday.
Really good , and sometimes needs to mention “CARBURETOR “ instead of carb
How to begins about
Funny, you can ‘know’ something but when someone lays it out so well it is really helpful. Nice job on the explanation.
Hey that was really helpful, thanks so much for your easy to understand explanations for those of us who aren't mechanics!
Great video - helped me yesterday with no choke and full throttle! Thanks!
Great video. Your common sense approach and the tips are great and will help a lot of boaters and fishers. Much appreciated.
You saved my summer!!! Thanks man very informative and you got me back on the water.
Thanks, This was very helpful with determining and fixing my flooding problem problem.
We found this video really helpful in our understanding of how an outboard works and why we were having problems starting our outboard. Thank you very much.😊
I have a basic understanding of how outboard carbs work but your simple language explanation really makes it very clear. Thank you so much. Keep it up.👍
Your tips really work on my Rescue Boat engine. Thank you so much.
Dude you are the best, my honda metropolitan laid on its side for like an hour and I know it's flooded but I don't know about carburetors. This helped me understand what's up.
