Stator for Mercury / Mariner 2-Stroke Outboards
Replaces Mercury 398-8778A29, 398-818535A10 and related numbers
A new aftermarket stator for Mercury and Mariner two-stroke outboards, including 70, 75 and 90HP three-cylinder and 100/115HP four-cylinder models, plus 90 and 120 SportJet. It replaces the 398-8778A and 398-818535A series stators.
The stator produces the charging current and, on many engines, the trigger supply for the ignition. A failing stator shows as no charge, a misfire that gets worse as the engine warms, or a dead cylinder that comes and goes.
Key Features
- 100% new aftermarket stator
- Replaces the 398-8778A and 398-818535A series

Frequently Asked Questions
How do I confirm this stator fits my engine?
Match the number on your existing stator, or your engine model and serial number, against the tables above. Engines within the same horsepower can use different stators by serial range, so send us your serial number if unsure.
Why does delivery take 5-7 working days?
This part is shipped to us from our European warehouse in Spain rather than held on the shelf in the UK. We dispatch it to you as soon as it arrives.
How do I know the stator is faulty?
Test the charge windings and, where fitted, the ignition windings with a multimeter against the service manual values. Check the regulator/rectifier too, since a failed regulator can mimic a stator fault.
