While Tohatsu does not provide a single universal service schedule, their standard practice for most four-stroke outboards involves an initial "break-in" service, followed by annual or 100-hour service intervals. It is crucial to consult the owner's manual for your specific model to get the exact maintenance schedule.
Typical Tohatsu four-stroke service schedule
Initial break-in service (20 hours or 1 month)
This service is critical for a new outboard to remove any debris from the engine as the internal parts set. The work typically involves:
After the initial break-in period, maintenance is generally required every 100 hours of operation or once per year, whichever comes first. This service includes:

This service is critical for a new outboard to remove any debris from the engine as the internal parts set. The work typically involves:
- Changing the engine oil and replacing the engine oil filter.
- Changing the gear oil in the lower unit.
After the initial break-in period, maintenance is generally required every 100 hours of operation or once per year, whichever comes first. This service includes:
- Change engine oil and filter: This is a routine part of maintaining engine health.
- Change gear oil: The lower unit gear oil should be drained and refilled.
- Inspect and change spark plugs: Spark plugs should be checked for wear and replaced if necessary, as they impact engine performance and fuel efficiency.
- Inspect and change fuel filters: Regular replacement of the fuel filters prevents clogs and ensures proper fuel flow.
- Inspect the water pump: The water pump, especially the impeller, should be inspected, and the impeller is often replaced as a preventive measure.
- Inspect the propeller: Remove the prop, check for fishing line or damage, and lubricate the prop shaft.
- Check steering and trim systems: Inspect these for excessive play, leaks, and proper function.
