Sierra Pre-Amp Trigger 18-99465 for Chrysler Outboard Ignition Systems, Replaces CDI Electronics 135-4048

The Sierra 18-99465 is a pre-amp trigger built for Chrysler outboard ignition systems. The trigger is a core component of the ignition system, generating the timing signal that the ignition module uses to fire the spark at the correct point in the engine cycle. As a pre-amp trigger, it works alongside the ignition module to condition and amplify this timing signal before it reaches the power pack, helping maintain consistent spark timing for reliable engine starting and running performance.

This trigger is a direct equivalent to CDI Electronics part number 135-4048, making it a straightforward replacement option for Chrysler outboard owners whose original trigger has failed or is due for replacement. It is a compact, lightweight component designed to install into the existing ignition system location on applicable Chrysler outboard engines.
