Basically they are valves that shut the flow of fluids into or out of your boat. They could be on :
Bilge drain outlets
engine cooling water inlets
onboard head water inlet
wash down pump inlet
etc.
The one on my boat lok no different than a large water faucet valve except they are bronze.
You may also have shut off valves on your engine fuel lines located at the fuel tank.
hope this helps
