⚠️ IMPORTANT – CARBURETTOR MODELS
This 879147T62 unit is for selected carburettor 10 HP, 15 HP and 20 HP engines.
Do NOT confuse it with the later EFI regulator / rectifier.
Selected later Mercury / Mariner:
- 9.9 HP EFI
- 10 HP EFI
- 15 HP EFI
- 20 HP EFI
use a different regulator / rectifier, including the 8M0134477 family.
If your engine is EFI, do not order this unit based simply on horsepower.
⚠️ Important – Check Before Ordering
Do NOT order this electrical component simply because:
- Your engine is 10, 15 or 20 HP
- Your serial number starts with 0R
- The regulator looks the same
Before purchasing, please check:
- Exact engine horsepower
- 4-stroke engine
- Carburettor or EFI
- Engine serial number
- Original rectifier part number
- Electrical connector
- Wiring configuration
- Mounting arrangement
Ideally, match your original part number to:
879147T62
If the part looks the same as the one fitted to your engine, this does not always mean it is the correct part for your outboard.
If you are unsure, contact SSI Marine with your complete engine serial number before purchasing.
Before Installing Your New Rectifier
If the original rectifier has failed, we recommend checking the charging system before installing the replacement.
Check:
- AC output from the stator
- Battery condition
- Battery terminals
- Engine earth / ground connections
- Stator wiring
- Fuse and fuse holder
- Electrical connectors
- Burnt or corroded terminals
- Melted or heat-damaged wiring
Repair any charging-system faults or damaged electrical connections before installing the replacement unit.
