Attwood Garboard Drain Plug Cast Bronze

The Attwood Garboard Drain Plug Cast Bronze (Model 7555-3) is a precision-engineered bilge drain solution designed for reliable water removal during haul-outs while maintaining a secure, watertight seal when closed. Built from cast bronze, this drain plug withstands the corrosive marine environment and delivers the dependable performance boat owners demand in critical drainage applications.

Key specifications include machined and tapered pipe threads that guarantee a watertight fit, a 3/8-inch neck depth, and a 1/2-inch NPT drain outlet sized for efficient bilge evacuation. The removable nut accommodates standard wrench or pliers operation, allowing quick access without specialized tools. Installation is straightforward—the plug secures with three #8 countersunk screws, eliminating the need for complex modifications to existing drain fittings. Bronze construction resists saltwater corrosion far better than ferrous alternatives, ensuring years of reliable service in freshwater and marine environments alike.

This drain plug is essential for weekend fishermen and serious offshore anglers who prioritize vessel integrity during seasonal layups and maintenance hauls. It addresses a fundamental boating need: preventing water accumulation in the bilge while the boat sits idle, which protects the hull and internal systems from moisture damage. For any boat operator managing routine bilge maintenance or upgrading drain reliability on an aging hull, the Attwood Garboard Drain Plug Cast Bronze delivers the precision fit and material quality that keeps critical drainage systems functioning as designed.
