Proper Yamaha Outboard Maintenance

Now that you have a better understanding of the types of oil available and why Yamaha lubricants are the best choice, you still may be asking yourself "When should I service my Yamaha engine?". Yamaha keeps it simple with clear maintenance milestones to follow

20-Hour Break In Service

For a brand new Yamaha outboard, you should change the oil and filter after ~20 hours of run time or within the first month, whichever comes first. This is critical because the break-in period creates particles that need to be flushed out early to protect your engine.

End of Season

Always change your engine oil before storing your boat for the off-season. Over time your system can collect mositure, contaminants, and combusion products. Leaving these in your outboard can lead to corrosion or unnecessary wear during storage. Fresh oil ensures your engine is protected while it sits for the next season.

Every 100 Hours of Use

For those who get to enjoy the water year round it is recommended to change your oil every 100 hours of run time. Regular engine maintenance helps keep your outboard clean, reduces strain on critical parts, and helps maintain reliable performance that Yamaha is known for.

Yamaha Outboard Oil Change Tip:

Warm up your engine before draining your oil, this helps contaminants flow out more easily and ensures for a cleaner oil change.

Yamaha Oil FAQs

► Can I mix different oils?

No, mixing can reduce protection. For the best results, stick with the same brand and oil type.

► How often should I change the oil in my Yamaha Outboard?

Yamaha recommends changing your oil every 100 hours of operation or once a year, whichever comes first. For new engines, the first oil change should be performed after 20 hours of use

► Do I need to change the oil filter every time?

Yes, the filter traps contaminants that can harm your engine. Skipping a filter change leaves old debris in your system and can reduce oil flow.

► What type of oil should I use in my Yamaha four-stroke outboard?

Use Yamalube FC-W certified oil that is recommended for your engine's size and operating conditions. Yamaha offers different viscosity options, such as 10W-30 or 20W-40, depending on the climate and application.

► Can I use automotive oil in my Yamaha?

It is not recommended. Outboards operate under higher loads in harsher conditions that car engines. Automotive oils are not designed for constant high RPM or saltwater exposure and may not protect your engine properly.
