ARCO Volvo Penta OMC Inboard Ignition Coil

The ARCO replacement ignition coil is specified for OMC inboard applications and is also identified for 1996 Volvo Penta use. It is intended to replace the original ignition component without changing the surrounding ignition-system design. Because inboard engine packages can share ignition parts across multiple marine brands, matching the old coil by part number is a useful confirmation step. The supplier positions this part as an OEM-quality service replacement rather than an ignition upgrade.

OMC 3854161 and 987680 are listed as the principal original-equipment cross references. The same application is also cross-referenced to Sierra 18-7492 and CDI Electronics E18-0010. Those interchange numbers can be helpful on engines that have already been serviced with an aftermarket coil. Before installation, compare the terminal arrangement, mounting method, and lead positions with the removed component.

Inspect the primary wiring, high-tension lead, grounds, and related ignition connections while the coil is accessible. Corroded or loose connections can create ignition symptoms that remain even after a new coil is installed. ARCO lists 12-month parts-and-labor warranty protection for the replacement part. Once fitted, verify starting quality and stable ignition operation under normal engine load.
