Stainless Steel Replacement Plug for Garboard Drain Assemblies
This stainless steel replacement plug is designed to replace a worn, damaged, or lost plug in an existing garboard drain assembly. At 1/2" thread size, it fits standard garboard drain bodies and provides a corrosion-resistant, watertight seal to keep your bilge dry when the boat is in the water.
Stainless steel construction offers superior corrosion resistance compared to brass or zinc plugs, making it a reliable long-term replacement for both freshwater and saltwater applications. Keeping a spare plug aboard is a simple precaution — a missing or damaged garboard plug is one of the most common causes of preventable flooding at the dock.

Parts Desk Insights
Best Use Case: The right sell when a customer has an existing garboard drain body in good condition but has lost, stripped, or corroded the plug itself. This is a common service item — plugs get left on the dock, cross-threaded, or corroded in place over time. Confirm the customer’s existing drain body accepts a 1/2" plug before selling; some older or non-standard assemblies use different thread sizes.
Stainless vs. Brass: This stainless plug is a direct upgrade over the brass plug included with many drain assemblies. Stainless holds up better in saltwater and is less prone to galvanic corrosion when used with a bronze or stainless drain body. Avoid pairing stainless with aluminum drain bodies — galvanic incompatibility can cause the plug to seize.
Spare Plug Upsell: A great add-on for any customer buying a drain assembly, bilge pump, or doing a bilge service. Recommend keeping one spare aboard — a lost plug at the ramp is a genuine emergency.
Miscategorization Fixed: This product was previously tagged under Tender & Trolling Motors — corrected to Pumps & Plumbing.
