Compatible Models
We do our best to list all compatible models. Although this may be the part you need, your exact model may not appear below.
Compatible equipment / model
- 1999–2005 Mercury 25 HP two-cylinder electric-start FourStroke within the listed serial range
- 2002–2005 Mercury 30 / 40 HP three-cylinder FourStroke within the listed serial ranges
- 2002–2005 Mercury 40 / 50 / 60 HP four-cylinder electric-start FourStroke within the listed serial range

Product Overview
An overcharging battery, low charging voltage, tachometer trouble, burnt connectors, or electronics that fail with RPM can point to the regulator. Battery condition, stator AC output, grounds, wiring, and accessory load must be tested first.
Horsepower alone does not confirm fit. Match engine serial range, cylinder count, EFI or electric-start configuration, six-wire plug layout, mounting, and every reference number.
Key Features & Performance
- Rectifies stator output and limits charging voltage on the matching outboard
- Application-specific electrical function for the listed circuit
- Reference, connector, pinout, and mounting details support a safer match
- Cross-references 893640T01, 893640-002, 830179T1, 830179T2 and related numbers

Compatibility Notice
Northline Parts does its best to list all known compatible models, but the correct part may fit an application not shown.
Model, production date, serial number, electrical or fuel-system version, dimensions, installed options, and previous repairs can affect fitment. Compare the original part and application information before purchase.
Frequently Asked Questions
Q: Will this fit every Mercury 40 HP outboard? A: No. Cylinder count, year, serial range, charging system, and plug configuration must match.
Q: Can a bad stator destroy a new regulator? A: A shorted stator, poor ground, overheated connector, or battery fault can overload the regulator, so test the full system.
Q: How do I confirm fitment before ordering? A: Match the original reference number where available, then compare the removed part, dimensions, connections, mounting details, model, serial or production information, and package photos.
Q: Is this an original-equipment part? A: No. This is a new aftermarket part. Brand names and reference numbers are used only to identify compatible applications.
