⚠️ Important – Check Before Ordering

Do NOT order this regulator / rectifier by horsepower or appearance alone.

Yamaha used different electrical and charging-system components on engines with the same horsepower.

Before purchasing, please check:

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

Ideally, match your original part number to:

6H2-81960-10

or

6H2-81960-10-00

⚠️ Appearance Does Not Confirm Fitment

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

Different Yamaha electrical components can look very similar while having different internal specifications.

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

Important – 2-Stroke Applications

This 6H2-81960-10 regulator / rectifier is primarily listed for selected Yamaha:

40 HP 2 Stroke
50 HP 2 Stroke
60 HP 2 Stroke
70 HP 2 Stroke

Do not confuse this component with the different regulator / rectifiers used on Yamaha F40 / F50 / F60 4-stroke engines.

Always check the original Yamaha part number.

Before Installing Your New Regulator / Rectifier

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

Check:

AC output from the stator
Battery condition
Battery terminals
Engine earth / ground connections
Stator wiring
Fuse and fuse holder
Electrical plugs and connectors
Burnt or corroded terminals
Melted or heat-damaged wiring

Any charging-system faults or damaged electrical connections should be repaired before installing the replacement unit.
