This foam plug should be on every sportfish or center console boat. Period. Safety is a must and this small piece of foam could save your boat.
Forespar Sta-Plug Foam Emergency Plug Sta-Plug® is a soft, cone shaped plug designed to conform to the irregular and unpredictable shapes of a hull breach. Whether it's a round hole caused by mechanical failure, or an elongated tear due to impact, it adapts to slow or stop the leak. Unlike old fashion wooden plugs, Sta-Plug's unique shape allows it to be compressed by hand or cut to fit. It also gets into hard-to-reach locations and can also be pushed into a gap using a screw driver or similar tool. It is the true stop-gap solution for emergency leaks. It is recommended to have 1 Sta-Plug for each 10' of boat length. Usable 10° to 275° F, -12° to 135° C. Not for fuel leaks.
