or seacock could result in a flooded boat. Next, remove
the “collector” or glass encasement that houses the
screen. Remove any objects collected inside and wash
the screen.
9.4.3 A/C Pickup and Strainer (Air Conditioning
Option)
At the end of this section, you will find an illustration of the
A/C cooling water arrangement. It is important to always
ensure that the intake valve (see mechanical arrange-
ment in the Boating Safety Chapter, as well) is always
open before using the A/C System. In the pumps sub-
section of this chapter you will see the image of these
components. Fig. 9.2.
If you purchased your boat with the air conditioning
option, you will find the documentation for the operation
of this system in the owner’s packet of the manufacturer’s
owner’s/operator’s manuals.
9.4.4 Generator Cooling Pickup and Strainer
(Generator Option)
The generator is an engine and, just like the main
engines, requires cooling water. Water is supplied to the
generator through the intake and strainer located just
aft of the generator. Raw water is taken in via the raw
water intake and then passes through the strainer and is
discharged through the exhaust of the generator. Consult
the DC Electric Chapter (Chapter 7) of this manual for
more information about your generator option.
9.4.5 Engine Seacocks and Strainers
It is a very important function for your main engines to
remain a specific temperature when operating. This is
done with the aid of raw water from the main engine
seacocks. Heat from the closed cooling system on the
engines is transferred to the cooler seawater through
heat exchangers inside the engine. The raw water is then
discharged through the exhaust.
To clean your main engine strainer, first close the main
engine seacock, remove the top cover on the strainer
remove the screen and clean.
CAUTION
!
!
Always ensure engine, or generator seacocks, or
intakes are open before starting. Failure to do so
could overheat and a damage these components.
More information concerning the operation and main-
tenance of this system can be found in the Waste
and Sanitation chapter, Chapter 10 of your Operator’s
Manual.
9.4 Pickups and Strainers
There are various pickups and strainers installed
aboard your boat. Here we will discuss the pick-ups
and strainers associated with the water systems.
9.4.1 Pick-ups
Pick-ups, or through hulls are placed in various locations
in the hull of your boat. The intakes usually have a ball type
valve which controls the flow of raw sea water to the spe-
cific component, or system associated with the pick-up.
CAUTION
!
!
It is very important that you ensure that the intake
valve is open before using a raw water supplied sys-
tem. Failure to do so could damage or break down a
system or component.
9.4.2 Strainers
Your boat is equipped with strainers that strain the raw
water taken in the thru hulls or pickups for objects that
could damage the impeller or pump equipment. Strainers
are equipped with a screen or a filter inside that collect
objects taken in. They must be cleaned as part of routine
maintenance.
To clean a strainer, first, make sure that the supply valve
is in the Off or closed position. Failure to close the intake

Note the
ball type valves.
When the handle
parallel to the
supply line then
it is in the open
position.
