5.6.2 Bilge pumps and drainage
Silver boats are equipped with an automatic electric bilge pump in
the location shown in Fig. 5. When the sensor detects the presence
of water in the bilge, the pump drains it automatically. The pump is
always in standby mode irrespective of the position of the main cir-
cuit breaker provided that the battery has been installed and con-
nected. The electric bilge pump can also be operated from the
switch panel. The capacity of the bilge pump is about 45 litres/min.
Boats without a manual electric pump installed do not feature an
automatic emptying function: in this case, the pump is engaged by
a switch in the switch panel.
The electric bilge pump is operated from the switch panel described
in Section 5.8.
Carry out regular checks to ensure that the ends of the bilge pump
suction hoses are not blocked by debris.
WARNING! The bilge pump system is not designed for controlling
leaks resulting from running aground or other such
damage.
CAUTION! Check the bilge pump regularly for correct operation.
Remove any debris from the pump suction inlets.

5.7.1 Engines
If the engine compartment in your boat is equipped with a fan, let it
run for at least 4 minutes before starting the engine as indicated in
the warning sign in front of the pilot. Also make sure that the ven-

5.6.1 Openings in hull and deck
The location of thru-hulls and related shutoff valves are indicated
in Fig. 5.
Silver boats are lined with a self-draining fibreglass interior.
The self-draining outlets in the aft corners of the interior must
be kept open and free from debris to ensure drainage. The Silver
Colibri is self-draining only when unloaded.
CAUTION! Despite self-drainage, water may find its way into the
bilge through motor well openings and inspection
doors. Check the bilge level before setting out to the
sea and drain it with the bilge pump provided.
On Silver Eagle, Silver Shark, and Silver Hawk 540,
the deck self-draining outlets can be closed with ball
valves. On the other models they can be closed with
plugs. If the boat is to carry a heavier-than-normal
load, close the self-draining outlets to prevent the
ingress of water.
With Silver Cab models, keep the cabin doors and
hatches closed in strong winds and heavy seas.
WARNING! If you want to keep the cabin roof hatch open when un-
der way, secure it in the open position with the locking
mechanism. Failing that, a sudden movement of the
boat may cause the roof hatch to close without warn-
ing and cause injuries. Secure all the other hatches and
doors in the same way.
