Description
SIERRA Oildyne Trim Pump Reservoir for MerCruiser – 18-6771 is a replacement fluid reservoir for compatible MerCruiser Oildyne power-trim pump assemblies. The reservoir stores hydraulic trim fluid and seals to the pump/motor assembly, making cracks, stripped fasteners or damaged sealing surfaces common reasons for replacement.
Published application data identifies this as the plastic Oildyne-style reservoir used on many MerCruiser trim systems from roughly 1983-2004. Verify the reservoir shape, mounting pattern and original number before ordering.
