⚠️ Important – Check Before Ordering
Do NOT order this regulator by horsepower or appearance alone.
Suzuki used different regulator / rectifier assemblies depending on engine generation, model and serial number.
Before purchasing, please check:
- Engine horsepower
- Exact engine model
- DF40 / DF50 – not DF40A / DF50A
- Model year
- Engine serial number
- Original regulator part number
- Electrical connectors
- Number of wires / plugs
- Mounting arrangement
Ideally, match your original regulator to:
32800-87J00
or
32800-87J10
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, 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 fitting the replacement.
Check:
- Battery condition
- Battery terminals
- Earth / ground connections
- Stator output
- Wiring condition
- Electrical plugs and connectors
- Burnt, melted or corroded terminals
Any charging-system faults or damaged connections should be repaired before installing the new regulator.
