Perko Garboard Drain Plug, 1 in NPT, Cast Bronze Flange, Steel Wrench

Overview

The Perko 0124000PLB is a garboard drain plug with a cast bronze flange, a brass plug, and a 1/2 in x 1/2 in square zinc-plated steel wrench. It is sized for a 1 in NPT drain opening, with a 1 in threaded neck, a 3-1/8 in outside flange, and a mounting pattern that uses #10 screws.

This is the style of drain fitted on the outside surface of the hull for draining water when the boat is hauled or on the trailer. For a replacement job, the details that matter most are the 1 in NPT size, the 3-1/8 in flange diameter, and the four-screw mounting layout, because those are the measurements that determine whether it drops into an existing installation without extra rework.

Key features

• Cast bronze flange with brass plug
• 1 in NPT pipe size with 1 in threaded neck
• 3-1/8 in outside flange diameter for checking footprint against the existing drain location
• Outside-surface mount that uses four #10 screws
• 1/2 in x 1/2 in square zinc-plated steel wrench included for plug removal and installation
• Separate service plug allows draining without removing the flange from the hull

Compatibility and fit

Check three points before ordering: the boat needs a 1 in NPT garboard drain, room for a 3-1/8 in flange on the outside surface, and a four-hole pattern sized for #10 fasteners. On older hulls, matching the flange diameter and fastener layout can save time because it reduces the chance of redrilling or leaving old holes exposed.

This plug makes sense for owners replacing a worn bronze garboard drain on a trailer boat, skiff, runabout, or small cruiser that already uses this format. It also works well as a full replacement assembly when the existing plug or wrench is missing.

Installation and use

The included wrench engages the square recess in the plug, so routine draining and reinstallation are straightforward at haul-out, storage, or pre-launch service. In normal use, the flange stays fixed to the hull and the plug is the part you remove and reinstall as needed.

Before fitting a replacement, it is worth confirming the outside mounting surface is sound and that the existing opening matches the 1 in NPT thread size. That is usually the difference between a simple swap and a repair that turns into a larger hull job.

Many products sold by Apollo Lighting include a manufacturer's warranty covering defects in materials or workmanship. Warranty terms vary by brand, product category, and model, so eligibility, coverage duration, exclusions, and available remedies are determined by the applicable manufacturer. We recommend reviewing the warranty information provided with your product before installation or use, especially for marine electronics, navigation equipment, lighting, electrical systems, pumps, safety equipment, and other specialized marine products.

If you need warranty service, the claim must follow the process established by the manufacturer, authorized service center, or designated warranty provider. You may be asked for proof of purchase, a serial number, product registration, photos, maintenance or installation records, or other documentation. Apollo Lighting does not determine or modify a manufacturer's warranty coverage or final claim decision, but we are happy to help provide purchase information and direct you to the appropriate manufacturer or warranty resource.

Keep your receipt, product documentation, serial number information, and original packaging when practical. Damage caused by normal wear, misuse, improper installation, insufficient maintenance, corrosion, impact, unauthorized modifications, electrical issues, or operation outside the manufacturer's specifications may not be covered. Warranty claims are separate from standard returns, so a product that has been installed, used, or exposed to marine conditions may no longer qualify for return while still remaining eligible for evaluation under the manufacturer's applicable warranty.
