WARNING
BEFORE DRILLING THE MOUNTING HOLE FOR THE SEA COCK THE
ENTIRE BOAT MUST BE OUT OF THE WATER. DRILLING THE SEA COCK
MOUNTING HOLE WITH THE BOAT IN THE WATER COULD CAUSE
EXTREME FLOODING AND SINK THE BOAT OR CAUSE SEVERE WATER
DAMAGE TO EQUIPMENT IN THE BOAT.

Once you are sure that all components will fit in the spot selected and remain below sea level and the boat is totally out of the water, you are ready to cut the sea cock mounting hole. (SEE WARNING ABOVE)
