Sierra Johnson Evinrude Power Pack Ignition Module

The Sierra Power Pack Ignition Module (also called an ignition power pack, CDM module, or ignition switch box) is an aftermarket replacement for Johnson and Evinrude outboard motors. It is a key part of the outboard ignition system. It takes the trigger signal and builds the high-voltage charge that the ignition coils send to the spark plugs, so the engine starts and runs reliably.

Key Features:

• Replacement power pack for Johnson and Evinrude outboard ignition systems
• Helps restore smooth starting, steady idle, and consistent spark delivery
• Engineered to match the form, fit, and function of the original equipment part
• Built for the heat, vibration, and moisture of marine use
• Backed by Sierra International, a long-established maker of marine replacement parts

A failing power pack can cause misfires, hard starting, a weak or missing spark, or an engine that cuts out. Replacing it with a Sierra module can restore ignition performance and help keep your outboard dependable on the water.
