90° Cockpit Deck Scupper Drain – Stainless Steel Grate, Nylon Elbow (50.8 mm)

When your boat’s deck or cockpit needs to shed water quickly, this 90° deck drain is up to the task. It is engineered to handle high volumes of water, such as heavy rain or waves washing over the bow, by channeling it off the deck through a hose. The visible part of the drain is a robust circular grate made of polished AISI 316 stainless steel, which not only stands up to corrosion in saltwater but also adds a quality finish to your deck. The grate’s “spoke” design is optimized for maximum flow while preventing large debris from entering the drain.

Underneath, the drain features a right-angle (90°) nylon elbow that attaches to your drainage hose. This integrated nylon adapter is strong yet lightweight, and it won’t corrode. It has a barb fitting that securely holds the hose, allowing the water to be directed either to a hull side outlet or to a collection sump. Because of the 90° angle, you can install this drain even in shallow spaces without needing a sharp bend in the hose. The drain has a generous 50.8 mm (2 inch) throat, ensuring water exits the deck as fast as possible – crucial for self-bailing cockpit systems.

• Self-bailing cockpits: Use this scupper drain in the cockpit floor of center console boats, RIBs, or fishing boats. Two of these drains (one on each side) can rapidly clear standing water, allowing the boat to remain self-bailing and stable.
• Deck showers and wet areas: Perfect for draining a shower area or washdown zone on deck. The stainless grate is comfortable underfoot and prevents items like hair or leaves from clogging the drain.
• High durability: For boats regularly exposed to harsh conditions (offshore fishing, sailing in rough seas), the stainless steel top resists wear and impact. The design ensures reliable drainage when you need it most, contributing to safety by reducing water accumulation on deck.
• Easy maintenance: The grate can be periodically removed (if the design allows) or cleaned in place to clear any trapped debris. Both stainless and nylon parts are low-maintenance; just rinse with fresh water occasionally to prevent salt and dirt buildup.

Whether you’re retrofitting an older boat or outfitting a new build, this 90° cockpit deck drain offers a professional-grade solution for deck water management. It meets the needs of serious boaters who require efficient self-draining capabilities and durable components. Installation requires cutting a hole (approx. 2 inch) in the deck and securing the drain (the stainless flange may be fixed with screws or sealant as needed, and the nylon elbow threads on from below). Once installed, it provides peace of mind that your cockpit will drain quickly and remain as dry as possible, even under heavy weather.
