Attwood Cockpit Drain - No Screen

The Attwood Cockpit Drain – No Screen is a marine-grade through-hull fitting engineered specifically for self-bailing cockpit systems on boats. Designed to integrate with 1-1/2" I.D. hose, this drainage component features a compact design that accommodates the tight dimensional constraints found in modern boat cockpits, making it an essential component for any vessel relying on gravity-fed water evacuation.

Built from polypropylene, the Attwood drain combines chemical resistance with lightweight durability—critical in saltwater environments where corrosion and UV exposure degrade lesser materials. The 3-3/4" stem length accommodates hull thicknesses up to 1-1/2", while the narrow 2-1/8" flange diameter and 1-7/8" installation hole size allow seamless fit into congested cockpit areas without requiring enlarged cutouts or structural modification. This compact footprint reduces installation complexity and maintains hull integrity around the through-hull opening.

The no-screen configuration makes this drain ideal for applications where unobstructed water flow is prioritized over debris exclusion—typical in racing, high-volume draining scenarios, or vessels operating in clean waters. Anglers and boaters who maintain their cockpits regularly appreciate the simplified maintenance this design offers compared to screen-equipped alternatives. The drain is a core component in any self-bailing cockpit system, working in concert with properly sized hose runs to automatically expel water as the boat's bow rises.

Attwood Marine through-hull fittings are trusted across the recreational and commercial marine industry for consistent performance in demanding saltwater and freshwater conditions. Proper installation—using marine-grade sealants and backing plates—ensures long-term reliability and prevents leaks that compromise vessel integrity.
