Self-Draining Neoprene Transom Valve (Nautispeed Automatic Drain Plug)
Say goodbye to manually pulling your boat’s drain plug every time you pick up speed – the self-bailing Nautispeed transom valve does it for you. This innovative drain features a neoprene one-way flapper that automatically opens when your boat is moving quickly (typically around 30 km/h or above). As the boat accelerates and water flows toward the stern, the valve flips open and allows any onboard water to rush out through the transom. Once you slow down or stop, the neoprene flap closes back up, sealing the opening so that outside water can’t come back in. It’s a simple yet effective solution that keeps your cockpit or bilge dry without any action required from you.
Constructed specifically for mounting in the transom drain hole, this automatic plug is a drop-in replacement for a standard drain plug in many small boats. The Nautispeed valve is made of durable materials – a corrosion-resistant housing and a flexible neoprene valve – designed to withstand repeated flexing and the marine environment. By installing this self-draining valve, you remove the hassle of remembering to pull the plug while underway, and you reduce the risk of taking on water if you forget to reinsert the plug after launching.
- High-speed self-bailing: Ideal for boats that can achieve planing speeds (e.g. sport boats, RIBs, water ski boats). At planing speed, water automatically drains out, which is particularly useful after taking splash or rainwater aboard.
- Hands-free convenience: Perfect for solo boaters or fishermen who want automatic bilge draining without needing bilge pumps, or as a backup to bilge pumps. The valve ensures the boat self-empties on the go.
- Safety and peace of mind: No more worrying about forgetting the drain plug. When stationary, the valve stays shut, acting just like a normal plug. When moving, it safely dumps water overboard, keeping the boat lighter and higher in the water.
This Nautispeed self-bailer is an excellent upgrade for small to medium-sized boats where simplicity and reliability are key. With a straightforward installation into the transom drain port, it provides continuous, worry-free drainage whenever you’re out enjoying higher speeds on the water.
