Quicksilver Cap - Oil Reservoir
The Quicksilver 865448A01 Cap Oil Reservoir is a genuine OEM part engineered as a direct replacement for the trim pump oil reservoir cap on a wide range of MerCruiser sterndrive and outboard engine applications. This yellow cap provides a secure seal for the trim pump reservoir, helping to maintain proper fluid levels and prevent contamination in the trim and tilt hydraulic system.
This part number has been superseded by part number 8M0188327. The superseded part is a functional replacement and may differ in physical appearance from the original. Buyers should confirm fitment using their engine or drive serial number prior to ordering. The cap is sold as an individual component and does not include the trim pump reservoir bottle.
Compatible with numerous MerCruiser pump motor assembly configurations, including Design I, II, and III top-mount and bottom-mount reservoir styles, as well as Bravo One, Bravo Two, Bravo Three, Bravo X, Bravo XR, and Bravo XZ outdrive variants, among others. Also used in select Mercury outboard trim pump assemblies.
