Common Outboard Engine Problems (and How to Avoid Them)

Any boat owner will tell you that one of the most critical pieces of equipment on their vessel is the outboard motor. It provides the power needed to get from Point A to Point B – which is why it needs to be reliable and durable enough to withstand long days out on the water. Here are some key steps for maintaining an outboard engine to keep it running smoothly for years to come – as well as how to avoid common causes of outboard engine repair.

How Often to Maintain Your Motor

Outboard Engine Repair in SheltonFirst and foremost, it is essential to check the level of oil in the engine regularly. This will help to ensure that the moving parts are properly lubricated and that the engine is running at peak efficiency. It is also a good idea to inspect the condition of the spark plugs and air filters regularly. When these components become dirty or worn, they can cause the engine to run rough or even fail altogether.

The cooling system will need to be flushed with fresh water every so often, especially before storing your boat for winter. This will help remove any salt or debris that could cause corrosion or other damage. The best way to ensure that you get the best possible boat maintenance services and keep your equipment in peak condition is to take it to an insured facility.

Common Outboard Motor Issues

Outboard motors are a vital part of any boat, but they can also be one of the most frustrating parts. They might refuse to start after being in storage all winter or quit working in the middle of a perfect day out on the water. While there are many potential causes of outboard motor problems, here are some of the most common issues:

Grime Buildup

One common problem with outboard motors is that they can be difficult to start. This is often due to a build-up of salt and grime on the engine, interfering with the ignition system. This can lead to extensive (and expensive) repairs, and it may even require the replacement of the entire engine. In addition, outboard motors are susceptible to fuel contamination, which can cause damage to the engine and potentially lead to fires.

To avoid grime buildup in your outboard motor, it is important to regularly clean and inspect the motor. It’s also important to check the oil level and quality regularly, as this can help to prevent grime buildup. If you notice any grime buildup, it is important to have the motor serviced by a qualified technician. By taking these simple steps, you can help to ensure that your outboard motor will continue to run smoothly for years to come.

Expired Gas

If you’re using an outboard motor that’s been sitting for a while, you may find that the gasoline has expired and is no longer usable. This can cause problems with the engine, including loss of power, poor acceleration, and misfiring. In extreme cases, it can even damage the engine. If you’re unsure about the quality of your gasoline, it’s best to play it safe and drain the tank before storing the motor. This will help to prevent any problems and keep your engine running smoothly.

Over time, gas can go bad and cause engine problems. Be sure to use fresh gas, and add a fuel stabilizer if you will be storing the boat for more than a few weeks.

Old Oil

Just like in your car, old oil can cause an outboard motor to run less efficiently. Be sure to change the oil according to the manufacturer’s recommendations. Check the oil level regularly and fill it up as needed. This will help keep the engine lubricated and protect it from wear and tear. Change the oil and filter according to the manufacturer’s recommendations. This will help to remove any build-up of dirt and debris. Check the fuel system for leaks or blockages to prevent problems with starting or stalling.

Spark Plug Issues

Maintaining your outboard motor’s spark plugs is important for several reasons. Dirty or worn-out spark plugs can cause your engine to run rough, reducing performance and fuel efficiency. Spark plugs that are not regularly replaced can eventually fail altogether, leaving you stranded on the water. For these reasons, it is important to periodically check and replace your spark plugs as needed. While this may seem like a hassle, it is a small price to pay to keep your outboard motor running smoothly.

Spark plugs can become fouled by oil and deposits, causing the engine to misfire. Be sure to clean or replace spark plugs as needed. This will ensure that the engine is getting enough spark for combustion.


Winterization is a critical process to undergo before storing your boat away for the winter. Freezing temperatures can cause the water in the engine to expand, cracking the block or other parts. In addition, the cold weather can damage the seals and gaskets, making it easier for oil and coolant to leak out. Another problem is engine seizure, which happens when the piston rings become damaged or broken.

Without proper winterization, the engine will be harder to start in the spring and will suffer reduced fuel efficiency and worse damage. So if you want to avoid costly repairs, make sure to winterize your outboard engine before storing it for the season.
