Sierra 18-5347 Marine Ignition Condenser, Strap Conductor, Replaces OMC 980894 and Mercury Marine 392-6324

The Sierra 18-5347 is a strap-conductor ignition condenser built for Chrysler Inboard tune-up applications using a Prestolite distributor. It is part of the Prestolite distributor system, which calls for two condensers per 12 volt ignition system, and it is functionally interchangeable with the Sierra 18-5340 condenser, which uses a wire-conductor design instead of a strap conductor. Buyers replacing a worn or failed condenser during a distributor tune-up can use the 18-5347 as a direct fit for the OEM part numbers it cross-references, including Chrysler Inboard, Mercury Marine, and OMC equivalents. The condenser is a compact, single-count component sized to mount within the distributor housing alongside the contact set, rotor, and cap during a full tune-up. It ships as a standalone part, so it should be paired with the appropriate contact set, rotor, cap, and ignition coil for a complete distributor rebuild. Because it is designed for 12 volt systems only, it should not be used on other voltage configurations. The strap-conductor design of the 18-5347 distinguishes it from the wire-conductor 18-5340, though both are interchangeable within the same distributor applications.
