From prolonging the life of your motor to preventing costly repairs, the right FourStroke outboard maintenance parts make all the difference.
What Maintenance Does a FourStroke Outboard Need?
Want to know how to do maintenance on a FourStroke outboard motor? Routine maintenance tasks include oil and filter changes, replacing spark plugs, and keeping the cooling system clean. Following the Mercury FourStroke maintenance schedule is crucial for preventing engine wear and tear, while also maximizing fuel efficiency.
For example, replacing your oil filter regularly helps remove contaminants and debris that could cause engine damage. Using the recommended Mercury outboard oil and filters guarantees your engine runs cleanly and at peak efficiency. Also, inspecting the gear lube and propeller shaft protects your motor’s drive system against corrosion and premature wear.
How Often Should I Change the Oil in a FourStroke Outboard?
According to Mercury’s maintenance schedule, oil changes should happen at least once a year or every 100 hours of operation, whichever comes first. However, in extreme conditions—such as boating in saltwater or when running at high speeds for long periods—you may need to change it more frequently.
The process involves draining the old oil, replacing the filter, and refilling with fresh oil. This is where quality products come in handy. When choosing oil filters and oils, be sure to use products that match your motor’s specifications for the best results.
Changing the oil at regular intervals will:
- Prevent engine wear
- Promote smoother performance
- Help with fuel efficiency
What FourStroke Outboard Parts Need to Be Replaced First?
Some parts of a Mercury FourStroke motor wear out faster than others and will need to be replaced sooner. Commonly, boat owners will first replace the following:
- Oil and Filters: Your motor's lifeblood, these should be replaced every 100 hours.
- Spark Plugs: Worn-out plugs can cause misfires and poor engine performance. These should be checked and replaced if necessary, especially if you notice difficulty starting the motor.
- Water Pump Impeller: If your water pump fails, your engine could overheat. Checking and replacing the impeller regularly helps prevent that.
- Gear Lube: This protects your motor’s lower unit and should be checked every season or before long outings.
Using OEM-certified parts is critical for your engine’s long-term health. Our FourStroke outboard maintenance parts meet Mercury’s exacting standards, which means you’re getting the same durability and reliability as the parts that came with your motor originally.
