Description
SIERRA 3-Wire Tilt & Trim Motor with Reservoir for Pre-1984 MerCruiser – 18-6763 is an older-style 12V three-wire power-trim motor supplied with its reservoir for compatible MerCruiser sterndrive systems. The assembly is intended for early hydraulic trim installations and does not include the separate pump valve body.
This part is commonly listed for MerCruiser applications through approximately 1984. Match the OEM interchange number and hydraulic pump arrangement before installation because later Alpha and Bravo systems use different motor/pump configurations.
