NOTE: There is an emergency shut-off fuel valve in the aft port cabin at the forward end of the bunk.
This is only to be used in the event that the engine will not shut down using the cockpit cut-off lever. If
you shut the engine down this way, you will need to bleed the air from the fuel line before it will start
again. This is a difficult and messy task!
(d) Engaging the transmission
Any time the black button on the throttle shift lever is pushed in, the transmission is not engaged. This
button works like the clutch on a manual shift car. To engage the transmission, one must bring the
throttle to the neutral position and the button will pop out. To go forward push the throttle forward, to
go in reverse pull the throttle back.
(e) Engine speed
The proper speed range for cruising is 1800 to 2500 rpm. Never run the engine at full throttle (3600
rpm). The best fuel efficiency is attained at engine speeds of 1800 to 2100 rpm. Always reverse slowly
and never use more than 2000 rpm in reverse. When in open water it is better for the engine to be run
at 2100 to 2500 rpm though this will use slightly more fuel. Diesel engines are not designed to be run
for long periods of time at low rpm. While you are sailing with the engine off, leave the engine in
reverse. This will lock the propeller giving much quieter sailing. In addition, if the transmission is left
in neutral while sailing the propeller will spin and cause unnecessary wear on the cutlass bearing.
(f) Fuel Supply
The main fuel tank holds approximately 50 gallons of diesel. On off shore passages an additional 20
gallons of diesel are carried in four 5 gallon plastic jerry cans stored in the starboard cockpit locker. A
ball siphon is in the locker with the jerry cans. To use it to siphon one inserts the ball check valve into
the jerry can and place the other end of the hose into the diesel fill fitting on the starboard fantail. Then
you simply shake the valve up and down four or five times. The fuel that you are siphoning enters the
tube on the down stroke and is prevented from leaving on the up stroke by the ball check. After a few
shakes the fluid fills the tubing until the siphon starts then you stop shaking the tubing and watch the
fluid flow. The pictures below show the ball siphon and how it is used to transfer fuel.
