Pick Your Location

This photo is showing the spot for the new seacock & thru-hull as chosen from inside the vessel.


1- Once you have chosen your spot drill through the hull from inside using a 1/4" drill bit. The reason for the 1/4" bit is that it matches the size bit used on most hole saws.


2- You then drill into the hull from outside using the proper sized hole saw to match the thru-hull. Start the hole saw in reverse as I have done here and you get no gelcoat chipping. Once through the gelcoat switch to forward and drill up through the hull making sure you are perpendicular to it.


other sizes: small medium large
