GROCO ARG-1250 Series 1-1/4" Raw Water Strainer w/Stainless Steel Basket

The GROCO ARG-1250 Series 1-1/4" Raw Water Strainer with Stainless Steel Basket is the reliable intake protection every serious boater needs to keep engine damage at bay. Whether you're running offshore, cruising coastal waters, or anchoring in shallow bays, debris—sand, shells, weed, and sediment—poses a constant threat to your raw water cooling system. This strainer intercepts contaminants before they reach your engine block, water pump, and heat exchanger, extending engine life and preventing costly mid-water shutdowns that can leave you stranded.

Built from marine-grade materials, the ARG-1250 features a stainless steel basket that resists corrosion in salt and brackish environments where standard steel would fail within a season. The tool-free mounting system allows rapid basket inspection and cleaning without disconnecting hoses or breaking your flow line—critical when you need to clear a clogged strainer in minutes, not hours. Dual bonding connections on both inlet and outlet sides ensure galvanic isolation and electrical safety, protecting against corrosion while meeting marine electrical standards. The compact 7 x 7 x 12-inch footprint fits tight engine compartments, and at 8.7 pounds, it mounts securely without adding significant weight or complexity to your raw water system.

This is the strainer for anglers and cruisers who understand that preventive maintenance beats emergency repairs every time. The 1-1/4" connection size accommodates standard through-hull fittings on most mid-to-large displacement diesel and gasoline engines. Installation is straightforward on new builds or retrofit applications; bonding lugs and O-ring seals all joining surfaces to eliminate weeping or bypass. Regular basket cleaning—typically every 50 to 100 running hours depending on water conditions—takes seconds and costs nothing, yet saves thousands in engine repair bills. For anyone serious about keeping their boat operational and their engine cool, the GROCO ARG-1250 is a proven, no-compromise choice.
