If you are looking for a guide on how to start a 2 stroke mercury outboard motor, then you have come to the right place. In this blog post, we will walk you through the process step-by-step.
It is important to follow these instructions carefully to avoid damage to your engine. Let’s get started.
What is 2 Stroke Mercury Outboard Motor?
A two-stroke Mercury outboard motor is an engine that uses gasoline and oil to create power. The fuel mixture is ignited by a spark plug, which causes the piston to move up and down. This, in turn, creates a rotational force that powers the boat’s propeller.
There are two types of mercury outboard motors: two-stroke and four-stroke. Two-stroke engines are simpler and more compact than four-stroke engines, producing more emissions and noise.
Four-stroke engines are more fuel-efficient and emit less pollution, but larger and heavier than two-stroke engines.
If you are looking to buy a new outboard motor, you will need to decide which type of engine is best for you.
How to Start a 2 Stroke Mercury Outboard Motor
You need to do a few basic things to start your Mercury outboard motor. Here is a guide on how to get started:
- Make sure the engine is in neutral gear
- Open up the choke by turning it all the way counterclockwise until it stops
- Turn on the ignition by rotating the key to the “start” position
- Depress the throttle halfway and wait for the motor to start
Once the engine is running, you can release the throttle. If it doesn’t start on the first try, don’t panic – keep trying until it does. And remember always to exercise caution when starting any engine.
How to Start a Mercury Outboard Motor in Cold Weather
To start a Mercury outboard motor in cold weather, you must take a few extra steps. The engine needs to be primed with fuel before starting, and the choke must be set correctly for the temperature outside. Here is how to do it:
- If the boat has been sitting unused for more than a day, remove the spark plugs and pour a small amount of fuel into each cylinder. You can use a syringe or turkey baster to do this.
- Replace the spark plugs and turn on the ignition without starting the engine. Hold down the throttle for about ten seconds.
- Now set the choke according to how cold it is outside. If it is below 50 degrees, set the choke to full on. If it is between 50 and 60 degrees, set it to half on. If it is above 60 degrees, do not touch the choke.
- Turn the key to start the engine and let go of the throttle. The engine may take a few seconds to start, so be patient.
- Once the engine is running, set the choke back to its original position. You can now start the engine by gently pushing down on the throttle.
If you follow these steps, your Mercury outboard motor should start up without any problems in cold weather.
Start a Flooded 2 Stroke Mercury Outboard Motor Engine
If your mercury outboard motor is flooded, you will need to take the following steps to start it:
- Remove the spark plugs from the engine. This can be done by using a socket wrench or pliers.
- Pour a small amount of gasoline into each cylinder. Be sure not to put too much in, as this could cause the engine to run too rich and flood it again.
- Replace the spark plugs and try to start the engine. If it doesn’t start, you may need to pour a little more gasoline into each cylinder.
Once the engine starts, be sure to rev it up slowly so that the fuel/air mixture can properly ignite. Once the engine runs, you can replace the plugs and tighten them down.
If your mercury outboard motor doesn’t start after following these steps, it may be time to take it in for repair. Contact your local marine dealer for more information.
How to Troubleshooting Your Mercury Outboard Motor
- If your engine will not start, you should first check the fuel level in the tank. Make sure that there is enough gas to run the engine and fill up if necessary.
- Next, check the spark plugs. A fouled plug can keep an engine from starting. Remove them and clean them with a wire brush or sandpaper. If they are too damaged, replace them.
- Also check the ignition system for problems. There may be a bad wire or connection that is preventing your engine from starting.
- Make sure the propeller is clear and not fouled with debris. Remove any weeds or other objects that may be caught in it.
- Finally, check the engine’s oil level. If it is low, add more oil.
If you have followed these steps and your engine will not start, take it to a qualified mechanic for further diagnosis. Do not fix it yourself unless you are experienced with outboard motors.
How to Avoid a Flooded Mercury Outboard Motor
One of the most common problems with a Mercury outboard motor is a flood. This means that too much gasoline has flowed into the engine, and it will not start.
There are several ways to prevent your Mercury outboard from flooding:
- Make sure you add the correct amount of oil to the engine. If there is not enough oil, the engine will suck in gas and flood.
- Be sure to use the choke when starting a cold engine. This will help to reduce the amount of gasoline that is ingested.
- If your Mercury outboard motor does flood, turn off the ignition and remove the spark plugs. Dump any excess fuel from the carburettor, and then re-insert the plugs. Finally, try to start the engine again.
If these tips do not help you prevent your Mercury outboard from flooding, there may be a more serious problem with the engine.
In this case, it is best to take your motor to a qualified repair shop for further assistance.
What If I See Smoke or Sparks Coming from My Engine?

If your engine still does not turn over, try wiggling the cord where it plugs into the motor – this can sometimes help get the starter going. If that does not work, you may need to have a mechanic take a look at it.
There are several things you can try. First, make sure the choke is in the “off” position, and the throttle is down.
Try giving the engine a few gentle taps with a hammer. If that does not work, you may need to have a mechanic take a look at it.

What if my engine will not turn over?
First, check the kill switch to ensure it is in the “on” position. If it is, and your engine still will not turn over, there may be a problem with your starter.
