ARCO IG017 Yamaha Mariner Outboard Ignition Pack

The ARCO IG017 ignition pack is a replacement control component for selected Yamaha and Mariner outboards. The supplier lists Yamaha 9.9 and 15HP engines from 1984-1995, C25 models from 1990-1997, and Mariner 9.9, 15, 20, and 25HP applications. Those ranges cover several ignition-system revisions, so the original pack number should be compared before installation. The IG017 is intended to restore the original ignition-control function without changing the engine’s underlying ignition design.

Yamaha 695-85540-11-00, 695-85540-12-00, and 695-85540-10-00 are listed as replacement references. Mercury/Mariner 43077T, 43077M, and 96450M are also included, along with Sierra 18-5131 and CDI Electronics 117-695-11. This cross-reference information is valuable when a previous repair has already replaced the factory pack with an aftermarket unit. Match the connector layout and mounting position with the removed component before final assembly.

Inspect the ignition harness, grounds, coil connections, and related trigger wiring when replacing the pack. A corroded connection or damaged lead can cause symptoms that resemble a failed ignition module. ARCO lists 12 months of materials-and-workmanship warranty coverage for leisure use and 90 days for commercial or racing applications when the part is properly installed. After replacement, confirm reliable starting and smooth operation through the engine’s normal speed range.
