Attwood Marine Replacement Garboard Drain Plugs, 1/2 in Diameter

Overview

This Attwood Marine garboard drain plug replacement plug is a threaded plug for compatible garboard drain assemblies that use a 1/2 inch NPT plug. It is used at the transom drain point so bilge water can be released when the boat is hauled, trailered, or stored, then sealed again before launching.

The plug uses machined, tapered pipe threads to help it seat tightly in the drain fitting. The nut can be removed or tightened with a wrench or pliers, which is useful when the plug is wet, cold, or hard to grip by hand around the stern.

Key features

• Replacement garboard drain plug for compatible 1/2 inch NPT drain fittings.
• Machined, tapered pipe threads help create a tight fit in the garboard drain opening.
• Hex-style nut can be handled with a wrench or pliers during haul-out, trailering, and seasonal service.
• Available in brass and stainless steel constructions to match the boat’s drain hardware and use environment.
• Pack sizes cover single-boat replacement needs and higher-volume service use.

Variants

This garboard drain plug is offered in multiple configurations so the same product family can cover routine replacements, shop inventory, and saltwater-focused service work.

The variants differ by construction and pack quantity. The 9844PD2 version is the stainless steel option marked for saltwater use, while the brass options are supplied in smaller and larger pack formats.

• 9842-3: Brass construction, pair pack quantity. This is the small-pack brass option for replacing plugs on an individual boat or keeping a spare set aboard.
• 9842PD1: Brass construction, 24 pair pack quantity. This bulk brass pack suits yards, dealers, and maintenance teams that service multiple boats with compatible garboard drains.
• 9844PD2: Stainless steel construction, 12 pair pack quantity, saltwater use. This version fits the same replacement-plug role in a stainless steel construction for boats operating in saltwater environments.

Compatibility and fit

Before installation, confirm that the existing garboard drain fitting accepts a 1/2 inch NPT threaded plug and that the plug construction matches the hardware already installed on the boat. Matching materials helps keep the installation consistent, especially around transom hardware that sees standing moisture, bilge residue, and washdowns.

This is a replacement plug, not a full drain fitting. The drain body, mounting hardware, and sealant condition should be inspected separately whenever the plug is replaced.

Use on board

This product is a practical fit for trailer boats, fishing boats, runabouts, and service yards that need replacement garboard plugs for haul-out drainage. It is also useful as a spare item to keep in a tool kit, since a missing or worn drain plug can delay launch day.

Apply normal marine maintenance habits around the drain area: keep the threads clean, check the seating surface before launch, and verify that the plug is installed securely before the boat goes back in the water.
