ARCO Early Yamaha 3-Wire 3-Bolt Tilt Trim Motor

The ARCO replacement tilt trim motor is made for early Yamaha outboards in the application range specified by the manufacturer. It uses ring-terminal electrical connections and a three-point mounting arrangement, along with a 4 mm thick shaft blade and a 68.3 mm mounting collar. An O-ring is included for the motor installation. Those physical details are valuable fitment checks on older Yamaha trim systems where several replacement motors can appear similar from the outside.

ARCO dynamically tests its tilt trim motors to verify operation before packaging. The motor shaft receives induction case hardening at the bearing surfaces to improve wear resistance, and the housing is epoxy powder coated for insulation protection. ARCO specifically recommends cleaning all electrical connections during installation because corrosion creates resistance and reduces the current available to the motor. That connection maintenance is especially important on older outboards that may have years of salt exposure around the trim system.

Yamaha 6E5-43880-01, 6E5-43880-02, 6H1-43880-00, 688-43880-10, and 688-43880-11 are listed as OEM cross references. Sierra 18-6259 and 18-6821 are also identified by the supplier. ARCO provides 12 months of defect coverage for leisure service and 90 days for commercial or racing use when the product is properly installed. Registering an eligible rotating-electric product within 30 days can add a further year of warranty coverage.
