1B5: Engine Room
Breakers (third from the bottom, left
row and third from the top, middle row)
in the ship’s AC and DC power panel on
the port side of the helm, and switches
inside and to the left of the door from the
companionway to the engine room turn on
the engine room lighting.
The engine room aboard Hele Mai is
accessed from the aft end of the guest
stateroom. There is adequate headroom to
allow easy access throughout, and space is
sufficient to get around the main engines.
The twin, turbocharged John Deere
four-stroke Diesel engines develop 135
horsepower each (maximum) and drive the
vessel via standard shaft arrangements on
each side of the vessel’s centerline. The
engine starting and house batteries are outboard and aft of each engine.
The port engine has the stabilizers’ hydraulic pump.
Among the numerous units and systems in the engine room are Flo-Jet
fresh and sea water pumps, an oil-change system, fuel manifold, sight
gauges on the fuel tanks, dual fuel filters for the main engines and a single
filter for the genset, a hot water heater, dripless shaft seals, starting,
generator and house batteries, sea valves, sea water strainers, and the
watermaker.
At the aft end of the engine room is a Westerbeke generator yielding
10,000 watts of 230/120 volts AC.
Fuel capacity for the engines and generator is 700 gallons in six tanks, 350
per side; a 100 gallon engine room aft tank, and a 250 gallon engine room
forward tank. A fuel manifold permits tank selection to use fuel as desired
as well as provide for trimming the vessel
(see “Fuel System,” page 46 for
a discussion of fuel management.)
This is truly a professional engine room up to the high standard of the
vessel!
