CR Marine's rubber molded "automatic drain plug" has kept Tempo's proven design, but improved the material. It is uniquely engineered to provide efficient drainage of a boat's hull. This four-part rubber product's defining feature is its unique duck bill flapper valve, which automatically drains water when the boat is underway. When inserted in a transom drain hole, this custom molded rubber plug will provide a water-tight seal as the boat slows or stops. The CR Marine automatic drain plug can be used with ease; It is removable, has no screws and is easy to check and clean.

Fits all standard 1" diameter drains on transoms up to 2-1/4" thick.
