Sierra 18-6752 Hydraulic Trim Pump Assembly, Metal Bracket, Replaces MerCruiser 14336A9, Fits 1983 and Later Without Quick Connect

The Sierra 18-6752 is a complete hydraulic trim pump assembly built for MerCruiser stern drives that use a low pressure, high flow trim system. It is designed as a full replacement unit, mounted on a metal bracket, and is engineered for boaters replacing a failed or worn trim pump rather than rebuilding individual internal components. The assembly is rated for use with a 20 amp fuse and is set up to pair with the Sierra 18-6772 tilt pump motor, which serves as the replacement motor for this unit. Low pressure, high flow hydraulic operation is matched to the demands of raising and lowering the drive unit and trim tabs on applicable stern drives, giving consistent trim response without the higher pressure requirements of quick connect style systems.

This pump assembly is intended for MerCruiser stern drives built 1983 and later that do not use a quick connect fitting, so it is important to confirm your drive's connection style before ordering. Because it ships as a complete assembly on its own metal bracket, installation follows the same mounting pattern as the original equipment pump it replaces, and it cross-references directly to a long list of MerCruiser stern drive trim pump part numbers.
