Sierra 18-5443 Ignition Coil - Cross Reference for Crusader, Mercruiser, OMC, Volvo Penta Engines

The Sierra 18-5443 Ignition Coil is a screw-in marine ignition coil built to meet or exceed the quality of the original equipment part it replaces. It is designed as a direct cross-reference replacement across multiple marine engine brands, making it a straightforward stock item for shops and owners servicing Crusader, Mercruiser, OMC, and Volvo Penta powerplants without having to track down a brand-specific coil.

The coil uses a male connector for a secure screw-in installation and is built to the same fit and function as the OEM coils it interchanges with. It is documented for use on the 377 Scorpion SKI 377/V-8 application within the serial number range K000656 - L00314 for the 1997-1998 model years, where it serves as the coil component of the ignition tune-up parts group for that engine.
