The Mercury OEM stator 398-5454A35 is a genuine factory electrical component used in the 16-amp charging systems found on many Mercury 2-stroke V6 outboards produced from 1976 through 1999. At Buckshot Racing #77, we supply this original Mercury stator as a reliable replacement for aging ignition and charging components on legacy Mercury performance engines.
The stator is a critical part of the ignition and charging system. It generates electrical power for the switch boxes while also supplying charging voltage to the battery and onboard electronics.
When a stator begins to fail, engines may experience weak spark, intermittent ignition loss, charging issues, or stalling once warm. Installing a new Mercury 398-5454A35 stator restores proper voltage output and dependable ignition performance across the entire RPM range.
Designed for Mercury 16-Amp Charging Systems
The 398-5454A35 stator was engineered for Mercury engines equipped with the 16-amp charging system, a configuration widely used on performance outboards running lightweight flywheels. These systems work with both steel 16-amp flywheels and lightweight aluminum racing flywheels, making them common on fishing motors and racing powerheads alike.
This stator fits all Mercury 2.0-liter and 2.4-liter V6 outboards equipped with the 16-amp electrical system, as well as any Mercury 2.5-liter V6 engine that has been configured with a 16-amp charging system. Many 2.5-liter performance engines—including race motors—use this lighter electrical system because it reduces rotating mass and supports high-RPM operation.
Compatible Mercury V6 Engines and Performance Models
The Mercury 398-5454A35 stator is used across a wide range of Mercury Marine and Mercury Racing V6 two-stroke outboards. It commonly appears on engines such as the Mercury 135 HP, 150 HP, 175 HP, 200 HP, and 220 Laser EFI, along with well-known performance models including the XR2, XR4, and XR6.
It is also widely used on Mercury Racing engines, including the 2.4-liter Bridgeport, SST-120, SST-140, 245 Carb, 260 EFI, and XRI performance powerheads. Because many performance builds convert to the 16-amp electrical system, this stator is frequently installed on 2.5-liter race engines and high-performance outboards as well.
These engines span the 2.0-liter, 2.4-liter, and 2.5-liter Mercury V6 platforms, which remain popular in bass boats, offshore performance hulls, and racing applications.
Mercury Part Number Interchange
The 398-5454A35 stator supersedes several earlier Mercury stator part numbers used over multiple production years. Compatible versions include 398-5454A66, 398-5454A36, 398-5454A34, 398-5454A33, and 398-5454A32, all of which share the same basic 16-amp charging system configuration.
Because of its widespread use, the stator also cross-references with several aftermarket replacements including CDI / Sierra 5456-16, Sierra 18-5860, and Mallory 9-25504, making it one of the most recognized stator replacements for Mercury V6 two-stroke engines.
Keeping Legacy Mercury V6 Outboards Running Strong
Many classic Mercury engines built on the 2.0L, 2.4L, and 2.5L V6 platforms are still widely used in performance boating and racing today. Electrical components naturally degrade over time due to heat cycling and vibration, which is why replacing the stator during ignition service or engine rebuilds is often recommended.
Installing a genuine Mercury stator 398-5454A35 restores proper ignition voltage and charging performance. For owners maintaining engines such as the XR2, XR4, XR6, Bridgeport, SST-120, 245 Carb, and 260 EFI, this stator remains a key component in keeping these legendary two-stroke outboards running reliably.
