Osprey
is equipped with a modern, computer
controlled, 5.9 Liter Cummins diesel engine.
This engine is extremely reliable and features
a turbocharger to boost total output to 380
HP. The output of the engine drives a 28”, four-
blade propeller through a 2.5:1 reduction gear
transmission. The prop is on the centerline
of the vessel with a modest keel and sizeable
rudder directly aft of the propeller. The engine,
controlled from the single-lever throttle and the
bow and stern thrusters are the primary controls
to manoeuver the boat.
Access
In the pilothouse deck, there are a pair of hatches. Usually it is sufficient to remove
just the forward hatch to gain access to the engine room. The engine room lights
are controlled by a switch at the helm. The engine room lights are long life LED
lights but please remember to turn them off when done in the engine room.
Pre-start checks
Before engine start each day, conduct a thorough inspection of the engine and
engine room, following the directions on the laminated Quick Start Procedures
(QSP) check-list located at the helm.
Starting
The Cummins engine requires no preheating
during normal seasonal conditions (see below for
circumstances that warrant the use of the engine
block heater). The engine key at the helm has two
positions “Off” and “Run”. Turn the key to the
“Run” position, wait for the “Smart Craft” display
to power up, acknowledge the display power-up
message, confirm the throttle / transmission lever
is in neutral (centered detent position), press the
start button and release when the engine begins
to run (usually less than two seconds of cranking).
Engine Control Functions
The engine control unit is electronic, and is operated via the chrome throttle
quadrant controls. The throttle lever controls the engine RPM and the illuminated
