Where Is The Choke On A Mercury Outboard

There are typically two chokes on a mercury outboard engine. The first choke is located on the carburetor and is used to help start the engine. The second choke is located on the fuel pump and is used to help the engine run at high speeds.

If you’re having trouble finding the choke on your Mercury outboard, don’t worry – you’re not alone. Many people have trouble finding the choke on their outboard, especially if they’re new to boating. The choke is actually located on the carburetor, and it’s usually a lever or knob that’s marked “choke.”

If you can’t find it, just look for the lever or knob that controls the amount of air that goes into the engine.

How do you choke a Mercury outboard motor?

If you’re looking to choke a Mercury outboard motor, there are a few things you’ll need to do. First, locate the choke knob on the motor. This is usually located near the carburetor.

Then, turn the knob to the “on” position. This will engage the choke and allow the engine to start. If the engine doesn’t start, turn the knob back to the “off” position and try again.

How do you choke an outboard motor?

If you’re having trouble with your outboard motor, one way to try and fix it is to choke it. Choking an outboard motor involves cutting off the engine’s air supply, which can sometimes help the engine to start up again. Here’s how you do it:

1. Locate the choke knob on your outboard motor. This is usually located near the throttle. 2. Push the choke knob in to the “on” position.

3. Start the engine. 4. Once the engine is running, slowly release the choke knob. 5. If the engine stalls, repeat steps 2-5.

If you’re still having trouble after choking the engine, it may be time to take it to a mechanic.

How do you start a 2 stroke Mercury outboard?

Assuming you have a 2 stroke Mercury outboard and you would like to know how to start it: To start a 2 stroke Mercury outboard, you will first need to make sure that there is oil in the engine. You can check the oil level by looking at the dipstick.

If the oil level is low, add oil until it reaches the full line on the dipstick. Next, you will need to connect the outboard to a power source. If you are using a boat, make sure that the battery is fully charged.

Once the outboard is connected to a power source, you can press the start button. If the outboard does not start, you may need to check the spark plugs. To do this, you will need to remove the spark plugs and check to see if they are dirty or damaged.

If they are dirty, you can clean them with a wire brush. If they are damaged, you will need to replace them.

Does a 4 stroke outboard have a choke?

No, a four stroke outboard does not have a choke. This is because the four stroke engine design is much different than that of a two stroke engine. In a four stroke engine, the intake and exhaust valves are located in the cylinder head, and the pistons are connected to the crankshaft via connecting rods.

The combustion process in a four stroke engine is different than in a two stroke engine, so a choke is not necessary.

How to start a 2 stroke mercury outboard motor

If you’re getting ready to start your 2 stroke mercury outboard motor for the first time, there are a few things you need to do to make sure it starts up correctly. First, check the oil level in the motor. If it’s low, add oil until it’s full.

Next, check the fuel level. If the fuel tank is empty, fill it up with fresh gas. Now it’s time to start the motor.

Make sure the kill switch is in the “on” position. Then, turn the key to the “on” position and push the start button. The motor should start right up.

If it doesn’t, check the fuel line to make sure there’s no blockage. Once the motor is running, let it warm up for a few minutes before revving it up. This will help prolong the life of your motor.

That’s all there is to it! Starting a 2 stroke mercury outboard motor is easy once you know what to do. Just make sure to check the oil and fuel levels before starting, and let the motor warm up before putting it under full power.

Mercury outboard electric choke not working

If your Mercury outboard’s electric choke isn’t working, there are a few things you can check to try to troubleshoot the issue. First, make sure that the choke is receiving power by checking the fuse. If the fuse is blown, replace it and try again.

Next, check the choke coil to see if it is burned out. If so, replace it. Finally, check the choke switch to see if it is defective.

If none of these things seem to be the issue, it is likely that the problem lies with the carburetor itself.

Boat choke not working

If your boat choke isn’t working, there are a few things you can check to try and troubleshoot the issue. First, check the fuel line to make sure there is no blockage. Next, check the carburetor to see if there is any dirt or debris preventing the choke from opening.

Finally, check the choke itself to see if it is damaged or not working properly. If all of these things check out, then you may need to replace the choke.


On a Mercury outboard, the choke is located on the carburetor. The choke is used to help start the engine by restricting the air flow to the carburetor, which allows the engine to get more fuel.
