As a safety measure, close all seacocks when
leaving boat for any length of time to impede water
ingress in the event of water hose failure.
! CAUTION
While being towed, you must close all main engine
and generator engine seacocks to prevent water from
being forced into the engine’s exhaust and causing
internal damage.

Seacocks and strainers provide cooling water to
the engines, generator and A/C units located
throughout the bilge area.
To open the seacock, turn the handle in line with
water flow (vertically). To close, turn the handle
against water flow (horizontally). The strainers
should be inspected frequently and cleaned out
when plugged. If operation of the air conditioning is
excessive it is important that the A/C unit strainers
are inspected more frequently than other strainers.
The seacock body should be inspected and
lubricated annually.

The rudder is the vertical flat surface aft of the
propeller that pivots about a vertical axis and
changes the direction of the boat through the
water. The rudder stuffing box prevents water
from leaking into the boat where the rudder
post enters the hull. Spot check for leaks
before and after using your boat.
