ARCO 1985-2006 Johnson Evinrude Ignition Coil

The ARCO replacement ignition coil is intended for a wide range of Johnson and Evinrude outboards built between the mid-1980s and 2006. The application list covers several two-cylinder engines, a 50HP three-cylinder application, multiple four-cylinder models, and higher-output six-cylinder engines. That range makes part-number verification especially useful because the same coil design appears across many horsepower classes and engine families. This is a direct ignition-system service component rather than a universal coil that should be adapted to an unrelated engine.

The supplier lists Johnson/Evinrude 583740, 583298, 583040, and 777664 as OEM replacement references. Sierra 18-5170 and CDI Electronics 183-3740 are also included in the cross-reference information. Using the original coil number is often the most reliable fitment check when engine model labels are faded or a prior repair has changed the installed component. The mounting and primary/secondary connections should match the removed coil before the ignition system is reassembled.

During replacement, inspect the plug leads, terminals, grounds, and surrounding wiring so a separate connection problem is not mistaken for a failed coil. Secure the wiring away from hot or moving components and verify that all terminals seat fully. ARCO lists 12-month parts-and-labor warranty protection for this replacement component. After installation, confirm smooth ignition operation across the engine’s normal running range rather than checking only for a single spark event.
