Starting an outboard motor isn’t just about turning a key; it’s an art that ensures your boat performs optimally on open waters. You’ll need to check that the engine is in neutral and the area around the propeller is clear of any debris or obstructions. While these steps might seem straightforward, the nuances of each can make a big difference in your motor’s performance and longevity.
What happens next in the startup process not only sparks your engine to life but also sets the stage for a smooth, enjoyable voyage. Let’s explore what specific actions you should take to master this crucial skill.
Attaching a Hose and Motor Flusher Muffs
Before starting your outboard motor, you’ll need to attach a hose to the motor flusher muffs to ensure proper water circulation.
First, locate the water intake on your outboard motor. This is typically on the lower unit near the propeller. You’ll see open vents where water enters the motor. Grab your motor flusher muffs—these are rubber cups connected by a metal clamp. Open the clamp and position the muffs over the water intake, making sure they’re snug and secure.
Next, take your garden hose and connect it to the nearest water source. Attach the other end of the hose to the inlet on the motor flusher muffs. Make sure the connection is tight to prevent any leakage. Once everything is securely attached, turn on the water. The water should flow freely through the hose, into the flush muffs, and then into the motor’s cooling system.
It’s crucial to ensure the flush muffs stay in place and the water flow is consistent. If they slip or the flow is interrupted, your motor could overheat, leading to damage. Always double-check that everything is secure before proceeding to start the engine.
Starting the Engine
Now that the water is flowing and the flush muffs are secure, you’re ready to start the engine.
First, ensure that your boat is in a neutral position; it’s crucial to avoid any sudden movements once the engine kicks in. Next, turn the key to initiate the ignition process. If your outboard motor has a choke, use it now, especially if the engine is cold. Applying the choke helps enrich the fuel mixture and facilitates a smoother start.
Once the engine is purring, slowly adjust the throttle. This is your control point for the engine’s power output. Initially, keep the throttle at a low setting as the engine warms up.
During these first few minutes, it’s important to listen for any unusual sounds. A smooth, steady hum indicates that everything is functioning properly. If you hear sputtering or knocking, it might be a sign to check the engine’s settings or consult a professional.

Flushing the Motor
After using your outboard motor, it’s essential to flush it to remove salt, dirt, and debris that can cause damage. Flushing helps maintain the motor’s health, especially if you’ve been running it in saltwater. Here’s how you can flush your outboard motor effectively.
Firstly, you’ll need fresh water and a flushing attachment, commonly known as ‘ear muffs’ or a flushing bag. Attach the muffs to the water intake on the lower part of the motor. Ensure they’re snug to prevent any water from leaking out. You can also use a flushing bag, which is placed under the motor. Fill the bag with water to cover the intake.
Next, turn on the water before starting the motor. This step is crucial to avoid running the impeller dry, which could cause damage. Let the motor run for at least five minutes. This allows the water to circulate thoroughly, cleaning out any residual salt and debris.
While the motor is running, check the water flow from the outboard’s telltale (water indicator). A strong, steady stream indicates that everything is working correctly.
After the flushing is complete, turn off the motor followed by the water. This routine care extends the life of your motor and ensures optimal performance.
Frequently Asked Questions
How to properly start an outboard motor?
To properly start an outboard motor, first ensure the engine is in the vertical, upright position to facilitate fuel flow to the carburetors. Next, squeeze the primer bulb on the fuel line until it feels firm, indicating that the fuel has reached the engine. Set the gear shift lever to neutral to prevent unintended movement.
Engage the choke to enrich the fuel mixture, which is particularly helpful for cold starts. For manual ignition motors, attach the kill switch lanyard to your wrist or life jacket to ensure safety. If your motor has a manual start, pull the starter cord briskly; for electric start models, turn the ignition key while pressing the engine choke, if applicable. Once the engine starts, gradually disengage the choke and allow the motor to idle, giving it time to warm up before engaging the gear. This procedure promotes the efficient and safe operation of your outboard motor.
How to start an outboard motor that has been sitting?
To start an outboard motor that has been sitting idle, begin by removing the airbox and lubricating all components, especially the throttle plates and control linkage arm springs, to ensure smooth movement. Next, drain any old fuel from the tank, as stale gasoline can degrade and attract water, leading to inefficiency and potential engine damage. After draining, connect a separate tank filled with fresh fuel to the motor. Inspect and, if necessary, replace the oil cylinders and spark plugs, as worn or corroded parts can hinder starting. Check the gear lubricant for contamination or water intrusion, replacing it if needed, to maintain proper gear function.
Ensure the oil levels are adequate, topping off or changing the oil as required. Connect the motor to a fully charged battery or use a battery charger to provide sufficient starting power. Before starting, attach a garden hose with motor flusher muffs to the water intake to supply cooling water during the initial run. Finally, start the engine and let it idle, allowing it to warm up and circulate lubricants thoroughly. This comprehensive approach helps in safely reviving an outboard motor after prolonged inactivity.
Do you start an outboard with the choke in or out?
To start an outboard motor, especially when cold, engage the choke by pulling the choke knob out or activating the choke lever to restrict airflow and enrich the fuel mixture, facilitating ignition. Once the engine starts, promptly push the choke knob back in or return the lever to its original position to allow normal airflow; prolonged use of the choke can lead to engine flooding or spark plug fouling.
For engines with an electric choke, this is typically engaged by pushing in the key while turning it to start. Always refer to your specific engine’s manual for precise instructions, as procedures can vary between models.
How to start a flooded outboard motor?
To start a flooded outboard motor, first ensure the engine is in neutral. Then, open the throttle fully to allow maximum airflow, which helps clear excess fuel from the combustion chamber. Crank the engine in short bursts of about 10 seconds, pausing briefly between attempts to prevent the starter motor from overheating.
This process, known as a “clear-flood start,” facilitates the combustion of surplus fuel. If the engine doesn’t start after several attempts, inspect the spark plugs for signs of fouling or wetness; cleaning or replacing them may be necessary. Additionally, verify that the choke is fully disengaged, as leaving it on can contribute to flooding. If these steps don’t resolve the issue, consult a marine mechanic to check for underlying problems such as leaking fuel injectors or faulty sensors.
Conclusion
To ensure your outboard motor serves you well for years, regular maintenance, including proper starting and flushing, is crucial.
You’ve learned how to start your motor effectively, ensuring it’s in neutral before you turn the key. This simple step prevents undue stress on the motor and extends its lifespan.
Remember, the way you start your motor can significantly impact its performance. Always check that the motor is in neutral and the area around the propeller is clear of obstructions and debris before starting. This not only safeguards the motor but also ensures your safety and that of those around you.
Consistent maintenance doesn’t end with a successful start. Regularly check your motor for signs of wear and address any issues promptly. By keeping up with these practices, you’ll minimize the risk of breakdowns and costly repairs down the line.
