⚠️ Important – Check Before Ordering

Do NOT order this regulator by horsepower or appearance alone.

Yamaha used different regulator / rectifier assemblies on engines with the same horsepower.

Before purchasing, please check:

Exact Yamaha engine model
Horsepower
2-stroke engine type
Engine serial number / prefix
Original regulator part number
Electrical connectors
Wiring configuration
Mounting arrangement

Ideally, match your original regulator to:

6H0-81960-00
or
6H0-81960-00-00

If the regulator looks the same as the one fitted to your engine, this does not always mean it is the correct regulator for your outboard.

If you are unsure, please contact SSI Marine with your complete engine model and serial number before purchasing.

Important When Replacing a Failed Regulator

If your original regulator / rectifier has failed, we recommend checking the charging system before installing the replacement.

Check:

Stator output
Battery condition
Battery terminals
Earth / ground connections
Wiring
Electrical plugs and connectors
Burnt, melted or corroded terminals

Damaged electrical connections should be repaired before fitting the replacement regulator.
