GROCO ARG-2500 Series 2-1/2" Raw Water Strainer Stainless Steel Basket

The GROCO ARG-2500 Series 2-1/2" Raw Water Strainer with Stainless Steel Basket is an essential intake protection system for any serious angler or cruiser relying on engine cooling water. After years on the water, you know that debris—sand, seaweed, shells, and sediment—can block cooling lines and kill an engine in minutes. This strainer intercepts that contamination before it reaches your raw-water cooling system, saving costly repairs and keeping you fishing or cruising instead of troubleshooting.

Built with a heavy-duty stainless steel basket and corrosion-resistant construction, the ARG-2500 resists saltwater degradation that destroys standard strainers after a season or two. The bonding connections on both sides ensure electrical continuity and hull protection, while the O-ring seals at all joining surfaces eliminate leaks that can compromise your engine compartment. Tool-free mounting allows quick basket removal and cleaning without breaking down the entire intake line—a real advantage when you're clearing a clogged strainer mid-trip and need to get underway fast.

This strainer is ideal for marine engines, inboard-outboard drives, and cooling systems using 2-1/2" raw-water intake ports. The 20-inch length accommodates standard engine room installations, and the rugged design handles both freshwater and saltwater environments without maintenance headaches. Whether you're running a fishing boat, center console, or cruiser in coastal or inland waters, the GROCO ARG-2500 Series protects your investment by keeping your cooling system clean and your engine running strong for years to come.
