Clean debris from the bowl and screen and rinse parts in fresh
water. Insert the screen, place the O-ring in the groove of the bowl
and screw the bowl on hand tight. Be sure to open the water valve
before starting the engine.
Some engines are equipped with a closed cooling system with a self-
contained reservoir for engine coolant. Self-contained systems are
equipped with a heat exchanger which uses raw water to cool the
coolant. All raw water systems are equipped with a valve and
strainer.
Bilge Pumps
Check your bilge pumps often to make sure they are operating
efficiently. There are two bilge pumps: one is at the rear of the boat
near the rudder and under the floor by the forward bulkhead
located next to the fuel tank. To keep the pumps from getting
clogged, remove any debris you find in the bilge. Wash the bilge
with a good biodegradable household detergent or a bilge cleaner
available at your Nautique dealer or a marine supply store. Rinse
with water with your bilge pumps running. If your pumps seem to
lag, remove the top of the pump from the base and check the
impeller to make sure there is no debris inside. See your dealer if
there is still a problem with the pumps.
