Seachoice 2-7/8" Scupper Valve Kit — Self-Bailing Cockpit Drain
Keep your cockpit draining freely and prevent water from washing back aboard with this complete scupper valve kit from Seachoice. The rubber flapper valve opens under the weight of standing water to drain the cockpit efficiently, then closes automatically to block reverse flow from waves or wakes. Designed for self-bailing cockpits, this kit includes everything needed for a complete installation.
Parts Desk Insights
This scupper valve is the correct choice for self-bailing cockpit drains on sailboats and powerboats where the drain exits at or near the transom above the waterline, or as a thru-hull cockpit drain. It is particularly well-suited to boats that take spray or green water over the deck regularly, where a one-way flapper valve prevents the constant back-flooding that occurs with open scupper holes. If your existing flapper is torn, stiff, or no longer sealing, this full kit replaces the retainer ring, flapper, and gasket in one go — no need to source components separately. Confirm your drain opening is 2-7/8" diameter before ordering.
