ZEUS INTAKE SEACOCK
STRAINER
TOP CAP
SEACOCK
OPEN
On the forward end of the Zeus propulsion unit is an
intake seacock. The purpose of the seacock is to let sea-
water into the engine via the strainer. The seacock handle
must be positioned (open) in line with the fi tting.
The strainer contains a basket style fi lter that protects the
engine(s) by catching debris. Both port and starboard en-
gines feature seawater strainers. A daily visual check of
the basket is recommended before each cruise.
If necessary remove any accumulated debris in the strain-
er basket. Turn the top strainer cap counterclockwise to ac-
cess the strainer basket. Lubricate the O ring by applying
a water pump grease. Hand tighten the strainer cap by
turning in a clockwise direction.
Make sure the intake seacock handle is positioned in the
closed position (vertical) before opening the strainer or
water will continue to be ingested into the vessel. Be sure
to open the seacock handle after cleaning the strainer bas-
ket.
See the strainer vendor documentation for more detailed
information.
