Sierra 18-6774 Trim Motor - Replaces 811628, 828708A1, 878265A6 - Design II/Ram 3 2-Wire Tilt/Trim Units

The Sierra 18-6774 is a high-performance cartridge, replaceable trim motor built for Design II and Ram 3, 2 wire tilt/trim units. It uses a squared style Eaton design, allowing the motor cartridge to be replaced without swapping the entire tilt/trim assembly. This motor is engineered to meet the demands of high horsepower outboard engines and to hold up in the marine environment, and it meets or exceeds the original equipment part it replaces.

The 18-6774 is a direct replacement for the OEM trim motor used on 2 wire, squared style Eaton tilt/trim units, and it pairs with wire harness 18-6823 for a complete connection. If your outboard uses a 2-wire single system, this is the correct trim motor for a Design II or Ram 3 unit; for 2-wire single systems outside that range, Sierra offers 18-6777 as a separate part.
