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.
CE Bilge Discharge Filter
Your boat may be equipped with a CE-compliant bilge discharge
filter system that is designed to prevent oil-contaminated bilge from
being discharged into the environment. One CE bilge filter is
required for each bilge pump. The CE bilge filter is located below
the deck, connected to the bilge discharge hose just before the
hose connection to the deck outlet fitting.
CE bilge discharge filter cartridge XOil™ replacement should be
part of a regular maintenance program to prevent oily,
contaminated bilge from passing through the deck outlet fitting
into the environment. The period between cartridge replacements
will depend on the condition of the bilge. Always replace the
cartridge immediately after there has been a great amount of oil or
other contaminants spilled into the bilge.
