ARCO Johnson Evinrude 4-Bolt Tilt Trim Motor

The ARCO replacement tilt trim motor is built for BRP-OMC Johnson and Evinrude FFI outboards from the late-model application range identified by the supplier. It uses a sealed female terminal connection and includes the O-ring needed at the motor interface. The four-point mounting arrangement matches the original-style installation used on the specified engines. This gives owners and service shops a complete motor replacement rather than a bare electric motor that requires adapting the original sealing hardware.

ARCO dynamically tests its tilt trim motors before packaging so the assembly is checked for operation before it leaves the factory. The motor shaft is induction case hardened at the bearing surfaces to improve wear resistance where the shaft carries the greatest mechanical load. An epoxy powder coating adds insulation protection to the motor assembly and helps shield it in the marine environment. ARCO also advises cleaning the electrical connections during service because corrosion adds resistance and can reduce the current available to the motor.

The manufacturer lists BRP-OMC 438786, 439937, and 5005254 as replacement references and also cross-references Sierra 18-6281. Those part numbers should be compared with the existing motor along with the terminal style and mounting arrangement before installation. Properly installed ARCO products carry 12 months of materials-and-workmanship coverage in leisure use and 90 days in commercial or racing service. The source notes that eligible rotating-electric products can receive an additional warranty year when registered within 30 days.
