⚠️ Important – Check Before Ordering
This stator is for selected Mercury / Mariner 2-cylinder 2-stroke engines.
Please check:
- Engine horsepower
- Complete serial number
- Original stator part number
- Electrical connections
- Wiring configuration
Ideally, your original stator should cross-reference to 86617A20 or one of the superseded numbers above.
Mercury used different stators across similar horsepower engines, so appearance alone does not confirm compatibility.
If unsure, send SSI Marine your engine horsepower + complete serial number + picture of the existing stator/connections.
