Brand: Volvo Penta

Overview
This is a genuine Volvo Penta OEM trim pump cover for use in Volvo Penta sterndrive trim and tilt pump assemblies. The pump cover forms the outer housing of the hydraulic trim pump, protecting the internal pump components and maintaining the sealed hydraulic circuit required for proper trim and tilt operation. As an OEM component, it is manufactured to factory specifications for fit, material grade, and sealing surface quality.
System
Hydraulic Trim & Tilt System – Sterndrive Trim Pump Assembly. This cover is part of the trim pump unit used to raise and lower the sterndrive. Confirm the exact assembly position against your drive's parts diagram before ordering.

Fitment Notice
Trim pump configurations vary across Volvo Penta sterndrive generations. Always confirm part number 21945911 against your drive serial number and the correct trim/tilt system parts diagram. Drive model alone is not sufficient to confirm fitment.
When to Replace
This pump cover typically requires replacement when it shows cracking, corrosion, stripped threads, damaged sealing surfaces, or physical damage from impact or over-torquing. It is also commonly replaced during a full trim pump rebuild when the cover shows wear that could compromise the hydraulic seal.
Installation Notes
Inspect the mating sealing surfaces and O-rings before reassembly. Replace any seals or O-rings disturbed during removal. Torque the cover fasteners to the Volvo Penta specification for the applicable trim pump assembly. After installation, cycle the trim system through its full range and check for hydraulic leaks before returning the vessel to service.
Parts Desk Insights
This cover is most often needed when a trim pump is leaking at the housing or when a full pump rebuild is underway. The most common issue is ordering the cover without also inspecting or replacing the internal seals and O-rings at the same time — if the cover is damaged enough to need replacement, the sealing surfaces and adjacent hardware are worth checking before closing everything back up. Pairing this with the Trim Pump 21945915 is the most common service combination.
