Sea-Dog Line Scuppers & Drains

When it comes to keeping your boat dry and properly drained, Sea-Dog Line offers one of the most comprehensive selections of scuppers and drains in the marine hardware industry. From self-bailing cockpit solutions to deck drainage systems, Sea-Dog's engineering focuses on reliable water management for vessels of all sizes.

Thru-Hull Scupper Valves for Self-Bailing Applications

Sea-Dog's thru-hull scupper valves mount through the transom to provide water exits for boats with self-bailing cockpits, featuring a soft black flapper that seals to prevent backwash. Constructed of injection molded acetal, these valves are engineered for above-the-waterline drainage and compatibility with most self-bailing applications. The round scupper valve design, particularly popular in center console and fishing boat applications, allows water to drain overboard while preventing reverse flow when the boat is at rest.

Deck Drains and Ventilation Solutions

Sea-Dog's deck drains are designed to drain water from cabin soles of bass, pontoon, and other open deck boats, and can also be used to vent lockers, refrigerator cabinets, or as a grille for enclosed horns and speakers. Constructed of UV resistant injection molded ABS, these versatile drainage covers serve multiple purposes beyond simple water evacuation, making them practical additions to any vessel's plumbing system.

Garboard Drains and Bilge Solutions

For haul-out drainage and bilge management, Sea-Dog manufactures traditional garboard drains in both machined and die-cast bronze. Their machined bronze garboard drain provides drainage for bilge during haul-out, with a ½" NPT tapered thread plug that provides a watertight seal. These drains feature practical design details like square-top plugs for socket wrench operation or T-handle versions for easy manual access from inside the boat.

Marine-Grade Materials and Construction

Sea-Dog products are constructed from durable, marine-grade materials designed to withstand harsh saltwater environments, including 304 and 316 stainless steel, investment cast bronze, chrome-plated brass, and UV-resistant injection-molded polymers. This material diversity allows boaters to select drainage solutions appropriate for their specific installation location and budget, whether prioritizing corrosion resistance, strength, or cost-effectiveness.

Why Choose Sea-Dog for Drainage Hardware

Sea-Dog Line's drainage products are engineered with practical installation in mind, typically designed for straightforward DIY installation with common fasteners. The brand's scupper valves work with standard 1-1/2" hose connections, simplifying replacement and retrofit projects. Whether you're upgrading an older vessel's cockpit drainage system, installing new deck drains on a pontoon boat, or maintaining bilge drainage during seasonal haul-outs, Sea-Dog's comprehensive catalog offers proven solutions backed by the company's reputation for quality marine hardware.
