GROCO BM-15 Monel Basket - 3.1" x 18.3"

The GROCO BM-15 Monel Basket is a marine-grade raw water strainer designed for serious cruisers and commercial operators who demand reliability in demanding saltwater environments. This basket-style strainer intercepts debris before it reaches your engine's cooling system, protecting your investment and keeping you on the water longer between maintenance intervals.

GROCO engineered the BM-15 from premium Monel alloy—a nickel-copper composition that resists corrosion far better than bronze or stainless in high-salinity applications. The basket's design allows for efficient straining while maintaining adequate flow rates for modern inboard and outboard cooling systems. Its cylindrical mesh design enables easy removal and cleaning without breaking hull connections.

This strainer basket suits vessels operating in saltwater, brackish, or sediment-heavy freshwater conditions where engine protection is non-negotiable. Commercial fishing boats, cruising sailboats, and charter operations benefit most from the GROCO BM-15, ensuring optimal performance and longevity in challenging environments.
