For the best performance and longevity, Yamaha recommends following its service schedule for your outboard motor. Intervals are based on operating hours or elapsed time, whichever comes first, to account for both active use and the degradation of fluids over time.
Initial 20-hour (or 3-month) service
This first service is critical for a new outboard to ensure a proper break-in period.
This service is a crucial routine interval for engine performance and a long lifespan.
This is a more in-depth service to ensure the engine operates at peak performance for the long term.
This service involves more extensive work to ensure the long-term reliability of the outboard.
