GREY LADY OPERATING MANUAL
NW Explorations
Outboard Motor
The outboard motor for the boat is a
8 hp
Yamaha
four-stroke unit.
Do not
mix oil with the fuel as it uses regular
gas only
.
If oil is low (this should seldom happen,
if ever!), stop the motor at once and
add oil.
To check the oil, remove the cover by
pulling out the lever on the back of the
motor hood and lift the hood off. You
will see the yellow dipstick for checking the oil. Use the motor oil supplied. (To avoid spills, you may need a funnel when
adding oil.)
Do not overfill!
Because of its power, operate the dinghy carefully at all times, it is “tender”!
Fresh Water System
Tank
There is a single water tank filled by a side
deck fill pipe on the port side amidships of the
boat marked “WATER”. This tank holds 300
gallons. You can use the freshwater gauge on
the Volvo Penta engine panel.
Be sure to use
the “water” not “waste” fill!
Water Pump
The water line from the tanks leads to the boat’s fresh water pump, located in the engine room. Provided the “F.W.
Pump” circuit breaker is “On”, the pump will run whenever its built-in pressure switch detects low water pressure. There
is also an “accumulator tank” by the pump; it provides a “pressure head” for the pump, so the pump doesn’t need to run
so often. Instead, a pump cycle will provide for several minutes of routine water use before pressure diminishes and the
pump starts again.
Water Heater
After the water pump, water is distributed directly to the cold water faucet lines. In addition, it goes to the boat’s water
heater. The heater uses two energy sources, (1) heat from the port engine, so that whenever the boat is running, or
has recently run, there is hot water; and (2) 110 volts AC from shore power or generator, if available and the heaters’
110volt AC breaker is “on”. The heater is insulated well enough to keep hot water overnight without power, provided
you haven’t wasted a lot.
Waste Water
Waste water from the sinks and showers (but not from the toilets) is dumped overboard in
accordance with U.S. and Canadian law. From sink basins, the water simply flows by gravity
overboard. Since the floor of the showers is below the water line, built in shower sump
pumps operate to lift this water back above the waterline and dump it overboard. There is a
“Holding tank” pump switch on the DC panel. To pump the “black water” overboard, please
read the Heads & Holding tanks section for proper disposal.
