What is the procedure to start an outboard motor that has been dormant for an extended period of time?

If you own an outboard motor, it is likely that it may be dormant for an extended period of time. Starting up an outboard motor that has been in the storage for a while can be a daunting task, especially if you’re a beginner. However, with the right procedure, you can get your outboard motor running smoothly in no time. Here is an article on the procedure to start an outboard motor that has been dormant for an extended period of time.

Step 1: Check the fuel

The first step in starting up an outboard motor that has been dormant for a while is to check the fuel. Over time, the fuel in the tank may go stale, which can cause problems for the engine. Therefore, if you have not run the engine for more than six months, it is advisable to drain the old fuel from the tank and replace it with fresh fuel. You can do this by removing the fuel line and draining the old fuel into a container. Then, replace the fuel filter and add fresh fuel to the tank.

Step 2: Inspect the engine

After checking the fuel, it is essential to inspect the engine thoroughly. To do this, you will need to remove the cowl and check for any signs of wear and tear, damage or corrosion. Check the fuel lines, spark plugs, and battery for any signs of damage or corrosion. Also, check the oil level and make sure that it is at the recommended level.

Step 3: Prime the engine

Once you’ve inspected the engine and replaced the fuel, you need to prime the engine. Priming the engine helps to push the fuel through the system and reach the carburetor or fuel injectors. How you prime your engine will depend on the type of fuel system your engine has. If you have a manual pump, pump the fuel bulb until it becomes firm. If your engine has an electric fuel pump, turn on the ignition switch, and let the pump run for a few seconds.

Step 4: Start the engine

After priming the engine, it is time to start it. Turn the key to the start position or pull the starter cord if you have a manual engine. If the engine doesn’t start after a few tries, stop and check the spark plugs. If they are wet, dry them off with a clean rag, then try starting the engine again.

Take note that the engine may take a while to start, especially if it has been dormant for a long time. Therefore, be patient and give it time to warm up. Once it starts running, allow it to run for a few minutes to circulate the fresh fuel and oil throughout the system.

Starting an outboard motor after an extended period of time may require some effort, but with the right procedure, the task can be done smoothly. It is essential to check the fuel, inspect the engine, prime the engine, and start it carefully. However, if you encounter any problems with the procedure, consult your owner’s manual or seek professional help.
