RPM Limiting Ignition Module
Some ignition modules are equipped with a built-in RPM limiting device, crucial for safeguarding your engine. Specifically, certain models, like the 1996 Johnson/Evinrude 25, 35 3-Cylinder outboards, feature a limiting ignition module to mitigate potential powerhead failures.
This module serves as a protective measure against various issues such as improper propeller selection (under propping), excessive wear on propeller blades, incorrect motor installation, propeller ventilation, or unusually light boat loading.
It's essential to utilize the correct ignition module when servicing these models to control the engine's operating RPM range effectively. This not only optimizes performance but also shields the engine from potential powerhead damage due to overspeeding.
RPM Limit: 6200

Troubleshooting the Ignition System
- Visual Inspection - Check wiring for broken, pinched, or loose leads. Ensure connectors are securely fastened and free from moisture or water accumulation.
- Test Equipment Condition - Verify that testers are in working order to avoid wasting time replacing functioning components needlessly.
- Follow Procedure - Consistency in troubleshooting techniques is paramount. By following a standardized procedure, all items in the ignition system are thoroughly tested, minimizing the risk of overlooking critical issues.
- Test the Complete System - Occasionally, multiple components may be defective. Detecting and addressing this ensures reliable ignition system performance, preventing repeat failures or damage to replacement parts.
