What Maintenance is Required on Outboard Engines in Ireland?

Outboard engines are a vital component of many boats in Ireland, whether used for fishing, leisure cruising, or commercial purposes. Of course, to keep an outboard engine running smoothly and efficiently, regular maintenance and servicing is required

But what are some of the essential maintenance tasks for outboard engines in Ireland?

From changing the oil and filter to inspecting the fuel and cooling system, there’s no doubt that regular maintenance is essential for an outboard engine.

With that in mind, we’ve compiled a comprehensive overview of the most important maintenance tasks for outboard engines in Ireland. So without further ado, let’s get started. 

1. Changing the Oil and Filter

Regularly changing the engine oil and filter is essential to keep the engine running smoothly. The frequency of oil changes can vary based on the engine model and usage. Still, it’s typically recommended to change the oil and filter every 100 hours of operation or once every six months (whichever comes first).

On brand-new outboard engines, an oil change after 20 hours of use is also recommended best practice. 

2. Inspecting and Replacing Spark Plugs

Spark plugs play a critical role in the engine’s ignition system, and worn or dirty spark plugs can lead to poor engine performance or difficulty starting the engine. Inspecting the spark plugs every 100 hours of operation or every six months is recommended, adjusting if necessary. 

For replacement, most spark plugs will last around a year before needing to be swapped out. 

3. Checking the Fuel System

The fuel system should be checked regularly for signs of leaks, clogs, or other issues that can impact the engine’s performance. This includes checking the fuel line, fuel filter, and fuel pump.

It’s also a good idea (regardless of issues) to clean the fuel tank and filter every 200 hours of operation or every year. Most fuel filters last two years before needing to be replaced.

4. Greasing and Lubricating Moving Parts

By lubricating the engine’s moving parts, such as the propeller shaft and other moving mechanical components, you can reduce friction and wear, which will help extend the engine’s lifespan.

Ideally, you should do this at least every six months, if not every 100 hours of operation (if that comes sooner). 

5. Inspecting the Cooling System 

The cooling system, including the water pump and impeller, should be inspected regularly to ensure that the engine is being cooled properly. Overheating can cause significant damage to the engine and reduce its lifespan. Check for blockages of the water inlet and other water cooling passages to ensure the system operates as it should.

Also, check for any coolant leaks and ensure the removable sea strainer is not clogged. Lastly, go through the hoses, clamps, and belts and ensure they’re all in good condition.

Due to the importance of the cooling system, you should be doing tasks such as checking for coolant leaks after every trip, but further inspections of belts, heat exchangers, and other parts are necessary every six months to a year. 

6. Flushing with Fresh Water

Another task that should be carried out every use is flushing the engine with fresh water. Not only does this prevent the buildup of salt and other minerals that can cause corrosion and other types of damage, but it also helps to clear out any debris that may have built up over time.

Failure to do so will likely result in corrosion and pitting within your cooling system. Without sufficient water flow to the engine, it will overheat and potentially seize up.

Put Your Outboard Engine in the Hands of Some of Ireland’s Best Mechanics

The last thing you want is for your outboard to let you down. Whether you’re readying your RIB for the spring or just about to head out on the water, you need to know everything under the lid of your engine is in tip-top condition. 

The tasks described above are only a fraction of the routine and preventative maintenance that should be done on an outboard engine, and it’s essential to have manufacturer-authorised mechanics to take care of both your routine and specialist needs.   

At Atlantic Boating Services, our best-in-class mechanics are trained and authorised to work on leading brands, including Mercury, Suzuki, and Yamaha outboards. Not only will our servicing cover all of the tasks mentioned above, but we’ll follow manufacturer guidelines and best practices to the letter, including using the latest diagnostic tools and software.
