Sierra Ignition Coil for Tohatsu Nissan Outboard Motors, 18-99271

The Sierra 18-99271 is an ignition coil built as a replacement part for Tohatsu and Nissan outboard motors. The ignition coil is a core component of the outboard's ignition system, generating the high voltage needed to fire the spark plugs and start the engine. Replacing a worn or failing ignition coil restores reliable spark delivery, which helps resolve hard-starting, misfiring, or stalling issues on affected Tohatsu and Nissan outboards. Sierra manufactures marine ignition and electrical parts to be a dependable, ready-to-install replacement for outboard owners and marine technicians performing ignition system service or maintenance. This coil is sold as a standalone replacement component, making it a straightforward swap when diagnosing or repairing ignition faults on compatible Tohatsu Nissan outboard engines.
