ARCO Yamaha 25-40HP 2009-Up Marine Starter

The ARCO replacement outboard starter is intended for Yamaha 25-40HP engines in the 2009-2022 application range supplied by the manufacturer. It is designed as a direct replacement for the original starting motor rather than an adaptation from a different engine family. Fitment should be confirmed by the engine model or original starter number before installation. The compact Yamaha application makes this part suitable for routine service when the factory starter has failed electrically or mechanically.

ARCO dynamically tests its starters so the unit is checked for operation before packaging. Nickel coating and/or epoxy paint is used to reduce corrosion, and the starter is sealed to help minimize water intrusion. The armature is tested to withstand 50 times its normal operating voltage, reflecting the manufacturer’s focus on electrical durability. ARCO also advises using a fully charged battery and cleaning every starting-circuit connection because weak voltage or added resistance can damage the starter and solenoid.

Yamaha 6BG-81800-00-00 is the OEM reference listed for this starter, with Mitsubishi M0TA5071 and Sierra 18-6964 provided as additional interchange numbers. Compare those references and the mounting arrangement with the old unit before installation. ARCO lists 12 months of warranty coverage for leisure use and 90 days for commercial or racing applications when properly installed. Eligible rotating-electric products can receive an extra warranty year when registered within 30 days.
