⚠️ 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.
