SeaCore Components and Castings
Mercury MerCruiser SeaCore power packages are equipped with additional stainless steel components and particular
aluminum castings with special coatings. Do not replace SeaCore components with non‑SeaCore. Use only the specified
Mercury MerCruiser SeaCore components and castings on these power packages.
Stainless Steel Fasteners
SeaCore models are equipped with additional stainless steel fasteners to maximize corrosion resistance in saltwater
environments.
Stainless steel fasteners are subject to galling when installed without lubrication. Galling can result in fastener destruction,
improper clamp loads, or both. Galled fasteners may appear to tighten properly, but still have incorrect clamp loads.
Apply a lubricant, such as 2‑4‑C or an equivalent, on the threads of stainless steel fasteners during installation to avoid galling.
Lubricate at least the first 6 mm (1/4 in.) of the threads before installation.
