Sierra 18-99226 Ignition Module for Nissan/Tohatsu 2-Cylinder 30-70 HP Outboards, 1980-1997

The Sierra 18-99226 is an ignition module built for Nissan and Tohatsu 2-cylinder, 2-stroke outboard engines. It serves as the ignition pack that controls spark timing and delivery for the engine, a component that must function correctly for the outboard to start and run smoothly. This module is designed for engines in the 30, 35, 40, 45, 50, 55, 60, and 70 HP range, built during the 1980-1997 model years, making it a broad-coverage option for owners of Nissan and Tohatsu 2-cylinder outboards in this power and production span.

As a direct ignition module, the 18-99226 is intended to restore ignition function on engines with worn or failing ignition packs, a common wear item on older 2-stroke outboards. The part is cataloged under Sierra's outboard ignition system line and weighs 1.1 pounds. Because Nissan and Tohatsu share engine platforms across this HP and year range, a single ignition module can serve both brands' outboards that fall within the stated specifications.
