GROCO BM-10 Monel Basket - 3.1" x 13.3"

The GROCO BM-10 Monel Basket is a replacement raw water strainer component engineered for marine engine cooling systems and saltwater intake applications. Constructed from high-strength Monel—a nickel-copper alloy—this 3.1" diameter by 13.3" length basket delivers superior corrosion resistance in harsh offshore and coastal environments where standard steel would fail. The improved handle design facilitates faster service intervals and simplifies basket removal during maintenance cycles.

Monel's inherent resistance to seawater corrosion makes it the material of choice for marine strainer applications where cost-effective stainless alternatives degrade under continuous salt exposure. This BM-10 replacement basket integrates with established GROCO raw water strainer housings, maintaining system pressure integrity while filtering sediment, debris, and biological growth from engine coolant intake lines. The 3.1-inch diameter specification fits mid-range strainer models, accommodating the flow demands of auxiliary engines and thruster systems on vessels ranging from 30 to 60 feet.

This basket addresses a critical maintenance need for boat owners and marine mechanics managing saltwater cooling systems. Scheduled replacement of strainer baskets—typically annually or after extended cruising seasons—prevents clogging and maintains cooling efficiency while preventing engine overheat conditions. The GROCO BM-10 is OEM-specification for ARG-2520 and 932-2000 strainer housings, ensuring fit and pressure rating compatibility. Whether performing preventive maintenance or emergency repairs underway, having a genuine replacement basket on hand extends engine service life and reduces downtime in remote anchorages.
