Sierra Ignition Pack 18-99232, Replaces Yamaha 6E5-85540-10-00, Fits 1984-1996 Yamaha 4 Cylinder 115 and 130 HP Outboards

The Sierra 18-99232 is an ignition pack (CDI unit) built for 1984-1996 Yamaha 4 cylinder outboard engines in the 115 and 130 HP range. The ignition pack is the electronic module that manages spark timing across the cylinders, and a failing or worn unit is a common cause of hard starting, misfires, rough idle, or a no-spark condition on these engines. Replacing the ignition pack with 18-99232 restores correct spark control without needing to replace the entire ignition system.

This ignition pack is a direct equivalent for the Yamaha OEM ignition packs listed below, so it installs using the factory wiring harness and mounting points on applicable 4 cylinder 115 and 130 HP powerheads. It is intended as a straightforward swap for outboard owners and marine technicians servicing these engines.
