Why won’t the outboard motor start after sitting?

When it comes to boating, one of the most frustrating things that can happen is being ready to go out on the water, only to find that your outboard motor won’t start. This issue is especially common after the motor has been sitting unused for a period of time. So,? Let’s take a closer look.

1. Old Fuel

One of the biggest culprits for a motor that won’t start after sitting is old fuel. Gasoline can start to break down after just a few weeks, and after a few months, it can become gummed up and clog the fuel system. This can prevent the fuel from flowing properly to the engine, leading to difficulty starting or even a failure to start at all. To avoid this issue, make sure you are using fresh fuel each time you take your boat out on the water.

2. Dirty Carburetor

Another common cause of starting issues with outboard motors is a dirty carburetor. If the carburetor is clogged with dirt, debris, or old fuel residue, it can prevent the engine from getting the fuel it needs to start properly. In some cases, the carburetor may need to be cleaned or even replaced to solve the issue.

3. Dead Battery

If your outboard motor won’t start after sitting, it may also be a problem with the battery. When a battery sits for an extended period of time without use, it can lose its charge, making it difficult or impossible to start the motor. To avoid this problem, make sure you are using a quality battery and keep it charged up when not in use.

4. Faulty Spark Plugs

Finally, faulty spark plugs can also cause starting issues with outboard motors. If the spark plugs are dirty, worn out, or damaged, they may not be able to ignite the fuel properly, resulting in difficulty starting or a failure to start at all. Spark plugs should be checked and replaced regularly to ensure they are in good condition.

There are several reasons why an outboard motor may not start after sitting. The most common causes include old fuel, a dirty carburetor, a dead battery, or faulty spark plugs. By understanding these issues and taking proper care of your motor, you can avoid starting problems and enjoy a smooth boating experience every time.
