GROCO BM-5 Monel Basket - 2.6" x 9.4"

The GROCO BM-5 Monel Basket is a marine-grade through-hull strainer designed to protect your engine cooling system from debris ingestion. This product is essential for anyone operating a boat with raw water cooling, particularly in environments where contaminants like kelp, sand, and shell fragments are prevalent. By installing this strainer basket at your through-hull fitting, you can significantly reduce maintenance issues and prevent overheating damage.

Constructed from monel alloy, a durable copper-nickel blend, the BM-5 offers superior resistance to seawater corrosion compared to standard stainless steel. Its design features a 2.6-inch diameter and a length of 9.4 inches, providing ample surface area for water flow while effectively trapping particles. The perforated structure allows for easy cleaning; simply remove the basket, rinse it out, and reinstall without needing to disrupt your through-hull fitting or shut down your cooling system.

This strainer basket is particularly beneficial for captains and engineers operating in saltwater or brackish-water environments, especially where sediment and algae are common. If your engine's raw-water strainer head is positioned below the waterline or in a high-flow intake area, the BM-5 serves as an effective pre-filter to enhance your engine's performance and longevity.
