EACOCKS
A ball valve seacock is installed on the inlet thru-hulls for the livewell, washdown, air
conditioning, generator, and head discharge systems. It is necessary for the seacock to be in the
open position to operate these systems. The open position is identified by the orientation of the
handle. If the handle is in line or parallel to the body of the valve, the seacock is in the open
position. If the handle is perpendicular to the body of the valve, the seacock is in the closed
position. The air and generator seacocks have remote arms installed on the handles. The open
position for these seacocks can be obtained by pulling up on the remote arm attached to the
seacock handles. Pushing down on the remote arm closes the seacock.
All seacocks should be in the closed position if not in use or if the boat is unattended to prevent the
taking on of water if a plumbing component fails.

ARD OP
Do not use the hard top for storing heavy or large items such as a raft. The frame for the top is
designed for continual use with antennas, radar, and outriggers. The additional weight caused by
larger items such as a raft may cause damage to the frame structure.
