⚠️ Important – Check Before Ordering
Do NOT order this regulator by horsepower or appearance alone.
Yamaha used different regulator and charging-system configurations across engines with the same horsepower.
Before purchasing, please check:
- Exact Yamaha engine model
- Horsepower
- 2-stroke engine type
- Number of cylinders
- Engine serial number
- Original regulator part number
- Electrical plugs/connectors
- Wiring configuration
- Mounting arrangement
Match the part number whenever possible.
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 unsure, contact SSI Marine with your complete engine model and serial number before ordering.
Important When Replacing a Failed Regulator
A failed regulator can sometimes be caused by another charging-system or wiring problem.
Before fitting a replacement, we recommend checking the condition of:
- Stator output
- Battery and battery connections
- Earth/ground connections
- Wiring
- Connectors
- Fuse and fuse holder
- Any overheated, melted or corroded terminals
Do not install a new regulator onto damaged or badly corroded electrical connections.
