Description
SIERRA Design II 3-Wire Tilt & Trim Motor for Mercury/Mariner – 18-6774 is a replacement electric trim motor for selected Mercury and Mariner Design II power tilt/trim assemblies. It is associated with the three-ram system, a replaceable motor, high-performance cartridge pump and the squared Eaton-style motor configuration.
