This oval stainless steel drain plug with base is an essential accessory to keep your boat’s bilge dry and protected. The sturdy oval flange sits flush against the hull and the removable plug screws in tightly to block any unwanted water ingress. A rubber gasket on the plug ensures a watertight seal, so even in choppy conditions or splashes, your bilge remains dry. When it’s time to drain the bilge (for example, after retrieving the boat from the water), simply unscrew the plug to quickly release the accumulated water. This drain plug is especially useful for smaller boats that don’t have automatic bilge pumps. The stainless steel construction is marine-grade and resists corrosion in both saltwater and freshwater environments, ensuring long-lasting performance for seasons to come.
- Use Case: Ideal for installation on the transom or lowest point of boats around 3–5 meters in length, such as fishing boats, small motorboats, and RIBs, where periodic manual draining of the hull is required
- Functionality: Provides a secure seal to keep water out of the hull while underway. When the boat is on land or after a trip, the plug can be removed to drain bilge water quickly and efficiently
- Advantages: The stainless steel material won’t rust, offering durability in harsh marine conditions. The oval flange covers a larger area around the drain hole, which helps distribute pressure and prevent leaks better than small round fittings
- Installation: Easy to install – drill an appropriate size hole and mount the flange using screws or bolts as needed. The low-profile oval design fits in tight transom spaces and adds a professional finish to your boat
- Recommendations: This drain plug is an excellent choice for trailerable boats and those stored on land between uses. For best results, periodically inspect the O-ring seal for debris or wear to ensure it continues to provide a leak-proof seal on every outing
