1B4: Engine Room
Preferred access to the engine room is through either the floor
hatch by the helm seat in the salon or by going forward and lifting the
stairs at the aft end of the companionway. DC breakers in the ship's
power panels turn on the engine room lighting. You will find this
engine room to have full stand up height with room to access most of
the systems and equipment.
Note: If you are going to be in the engine room a long
time, use the understair access and leave the hatch
down to prevent someone from falling in!
Along the forward
bulkhead from port to
starboard is the hot water tank
with the Kabola furnace above
it, then the hand washing sink
with the watermaker control
system above it, and fresh
water faucet,
then the companionway-
engine room door. To right of the door is the Naiad stabilizer
control unit and hydraulic reservoir with level indicator and temperature gauge.
To starboard (right) of the Naiad system is a battery
switch panel with isolator above, and just aft of it, the
clothes dryer.
Starting down the outboard starboard side of the
engine are battery boxes, spare parts boxes, wiring
panels with the Glendinning synchronizer and Whale
manual bilge pump above, then the battery chargers. Aft
just forward of the starboard tank enclosure is the
heating system hot water manifold with its regulating
valves and its water-conditioning unit (like a filter).
Outboard of this manifold is the starboard engine's
aqua-lift muffler.
On the forward face of the starboard fuel tank is
a control box, and engine room vent blower, and the
built-in fire extinguishing system, and just inboard of the
extinguisher is the tank's fuel sight gauge with valves at
top and bottom (that should be kept closed when the tank levels are not actually being checked.)
Of course, also to starboard of the engine room centerline is that side's Caterpillar 3126, 420hp
6-cylinder Diesel Engine. The engine is fitted with a Twin Disc marine transmission.
The drive coupling from the transmissions is connected to an Aqua-Drive universal-joint
vibration control with a thrust bearing affixed to the engine stringers. The aft end of the drive system is
