⚠️ Important – Check Your Existing Regulator
Please do NOT order this regulator by horsepower alone.
Mercury and Mariner used different electrical and charging systems across engines of the same horsepower.
Before purchasing, please check:
- Engine horsepower
- 2-stroke or 4-stroke
- Number of cylinders
- Engine serial number
- Original regulator part number
- Electrical plug / connector
- Wiring configuration
Ideally, match your original part number to one of the references in this listing.
If the regulator looks the same as yours, this does not always mean it is the correct regulator for your outboard.
If unsure, please contact SSI Marine with your engine serial number and/or original regulator part number before ordering.
Important Information for Older Engines
Mercury issued service information regarding replacement of earlier voltage regulators in this family.
On some older engines, the installation depends on whether the engine already has the appropriate fuse harness fitted. Mercury's bulletin states that where the fuse harness is already installed, 893640001 can be used as the replacement regulator; engines without that harness may require additional components appropriate to the application.
Therefore:
If replacing an older regulator such as 883071T1, please check your existing wiring/fuse-harness arrangement before purchasing.
If you are unsure, send us your engine details and photographs of the existing regulator and connectors.
