GROCO BM-2 Monel Basket - 1.9" x 7.2"

The GROCO BM-2 Monel Basket is an essential through-hull strainer component designed to protect your marine engine's cooling system and raw water intake from debris, marine growth, and sediment. Built for serious boaters and commercial vessels, this strainer basket prevents costly engine damage and cooling system blockages that can force you off the water mid-season. Whether you're running a fishing charter, cruising offshore, or maintaining a working vessel, a reliable strainer basket is non-negotiable insurance for trouble-free operation.

This basket is constructed from marine-grade Monel, a corrosion-resistant copper-nickel alloy that withstands saltwater exposure and harsh bilge environments without deteriorating or requiring frequent replacement. The 1.9" x 7.2" design provides ample surface area for water flow while maintaining fine mesh screening that catches everything from sand and shell fragments to kelp and fishing line. GROCO's engineering ensures low pressure drop across the strainer, maintaining optimal cooling water circulation even when moderate debris accumulation occurs—meaning you can fish harder before needing to service the basket.

Anglers, charter operators, and commercial fishermen rely on the BM-2 to work with standard GROCO through-hull seawater strainer housings found across most marine cooling systems. Installation and cleaning are straightforward—the basket sits inside the strainer bowl, accessible without breaking the entire through-hull fitting. This ease of maintenance makes it a preferred choice for those who depend on reliable performance in demanding marine environments.
