GROCO BM-12 Monel Basket - 3.1" x 11.9"

The GROCO BM-12 Monel Basket is a marine-grade intake strainer designed to protect your vessel's through-hull fittings from debris, sediment, and biological fouling. Built for serious anglers and boaters who depend on reliable cooling and water intake systems, this basket serves as your first line of defense against clogged seacocks and engine damage.

Constructed from Monel—a corrosion-resistant copper-nickel alloy—the BM-12 basket withstands saltwater, brackish, and freshwater environments without degrading or requiring frequent replacement. The open-mesh construction allows water to flow freely while trapping shells, kelp, mud, and other particulate matter that would otherwise lodge in your seacock or strainer housing, extending equipment life and preventing costly mid-trip shutdowns.

Boaters who run extended trips in variable water conditions benefit most from upgrading to the GROCO BM-12—especially those anchoring or fishing in silty bays, mangrove areas, or near shell beds where debris accumulation accelerates. Installation is straightforward: the basket drops into standard GROCO through-hull basket strainers and similar marine intake housings, ensuring a reliable fit.
