through the large drain hole in the
deck. A one-way check valve in the
drain prevents water from traveling
back to the deck during mooring or
while moving in reverse.
Bilge Pump –
1
Your Sport Boat is equipped with a
drainage system that channels water
that enters the boat from the storage
compartments to the bilge under the
engine compartment. When the bilge
pump is turned on (see page 2-11), the
pump will sense when there is exces-
sive water in the bilge and will auto-
matically drain most of it through the
outlet 1. For normal operation, turn
the bilge pump switch on during boat
use and turn it off when leaving the
boat.
CAUTION:
If the Sport Boat is to be left in the
water after use, leave the bilge
pump switch in the ON position. The
pump will activate if needed to drain
any water accumulating in the bilge.
Drain Plug –
2
A drain plug is located at the center of
the stern to allow more complete drain-
ing when the boat is removed from the
water.
Engine Compartment and
Fuel Compartment Drain Plug –
3
Water will not normally enter the
engine compartment or fuel compart-
ment areas during operation. If it does,
open the drain plugs 3 and allow
water to drain. Also open the engine
compartment plug when flushing the
engine area with fresh water after salt
water operation.
CAUTION:
● Excessive water in the engine
compartment bilge can splash
into the carburetor and engine.
This could cause engine damage.
● Be sure all drain plugs are tight-
ened before operating your Sport
Boat.
WARNING
Gasoline and its vapors are highly
flammable and explosive. If a fuel or
a fuel/water mix drains from the fuel
tank compartment drain or is found
in the engine compartment, wipe it
up immediately with dry rags. Do not
operate the boat until the source of
the fuel leak is found and corrected.
