ARCO IG026 Yamaha 115-225HP Ignition Coil

The ARCO IG026 ignition coil is designed for Yamaha outboards in the 115-225HP range that use the 6E5-series coil. The supplier specifically lists L200, L150, L130, 115, 130, 150, 175, 200, and 225 applications. That model spread includes several engine configurations, so the old coil number and connector arrangement should be checked along with horsepower. The replacement keeps the original ignition-system design intact rather than converting the engine to a different coil style.

Yamaha 6E5-85570-11-00 and 6E5-85570-10-00 are the OEM references listed for this part. Sierra 18-5110 and CDI Electronics 187-6511 are also identified as interchange numbers. These cross references provide a quick way to confirm the correct part on an engine that has already had ignition work. The mounting points and high-tension lead arrangement should match the removed coil before installation.

Check the primary connector, plug lead, grounds, and surrounding harness for corrosion or heat damage while the coil is accessible. A connection problem elsewhere in the circuit can create the same symptoms as a failed coil and should be corrected at the same time. ARCO lists 12 months of warranty coverage for properly installed leisure-use products and 90 days for commercial or racing applications. After installation, verify consistent ignition performance under normal engine load.
