Watertight Boat Drain Plug with Plastic Base – Ø23 mm (White/Black)

This drain plug with plastic base is designed to keep your boat’s interior dry and protected. The base mounts permanently on the transom or hull (typically at the lowest point), secured with screws, while the male plug screws in tightly to create a watertight seal. Thanks to the built-in hose barb on the inside of the base, you can attach a hose to direct drained water safely out of the boat (for example, channeling water to exit at the stern). This allows for quick, controlled bilge drainage and prevents water from pooling in hard-to-reach areas.

Made from marine-grade nylon plastic, the assembly is highly resistant to corrosion, UV degradation, and temperature fluctuations. The plug’s O-ring ensures a tight, leak-free closure even in rough waters or under stress. The drain plug can be opened easily by hand, enabling you to swiftly release any collected water when the boat is on land or when needed at dock.

Usage: Ideal for a wide range of small and mid-sized boats – from inflatables and RIBs to fishing and recreational motorboats up to roughly 5 m in length. Install the base securely at the transom’s lowest point. Always ensure the plug is screwed in and sealed before launching your boat. After pulling the boat out of water or following heavy rain, simply unscrew the plug to drain the bilge. The white plug version is perfect for light-colored hulls, while the black version suits darker hulls – both provide identical performance, so you can choose based on aesthetics.

For added safety and peace of mind, consider keeping a spare insert plug on hand (an identical male plug sold separately). In case the original gets misplaced or wears out, you’ll have an immediate replacement, avoiding any risk of water ingress. This drain plug system offers a reliable, must-have solution for bilge drainage and helps maintain your boat in top condition.
