Sierra Ignition Module for Tohatsu Nissan 2-Cylinder Outboard Motors, Part 18-99274

The Sierra 18-99274 is an ignition module built for Tohatsu Nissan 2-cylinder outboard motors. The ignition module is a core component of the engine's ignition system, responsible for triggering spark delivery at the correct timing so the outboard starts reliably and runs smoothly. When an ignition module begins to fail, outboard owners typically notice hard starting, intermittent misfires, stalling, or a complete no-spark condition, and replacing the module with a correctly matched part restores normal ignition function.

This module is designed specifically for 2-cylinder Tohatsu Nissan outboard applications, so it is sized and wired to match the ignition demands of that engine configuration rather than being a universal, one-size-fits-all part. Installing the correct module for your specific cylinder count and engine family is important for proper ignition timing and long-term reliability.
