Westerbeke 50 User Manual

for the supply line and the return line. Run the tubing in the
longest pieces obtainable to avoid the use of unnecessary fittings and
connectors. The shut off valve in the line between the fuel tank and
eng ine should be of the fuel oil type, and it is important that all
joints be free of pressure leaks.
Keep fuel lines as far as possible from exhaust pipe for minimum
temperature, to eliminate "vapor locks".
The fuel piping leading from the tank to the eng ine compartment
should always be securely anchored to prevent chafing. Usually the
copper tubing is secured by means of copper straps.
The final connection to the eng ine should be through flexible
rubber hoses.
ELECTRIC PANEL
The Westerbeke all-electric panel utilizes an electronic tacho-
meter wi th a built-in hourmeter. Tachometer cables are no longer
required, except for the Skipper mechanical panel. Mounted on the
panel are a voltmeter, water temperature gauge and ~il pressure gauge.
Each instrument is lighted. The all-electric panel is isolated from
ground and may be mounted where visible. It is normally pre-wired.
ELECTRICAL EQUIPMENT
Most Westebeke eng ines are supplied pre-wired and wi th plug-in
connectors. Never make or break connections while the engine is
running. 'Carefully follow all instructions on the wiring diagram
supplied, especially those relating to fuse/circuit breaker require-
ments.
Starter batteries should be located as close to the engine as
possible to avoid voltage drop through long leads. It is bad practice
to use the starter batteries for other services unless they require
low amperage or are intermittent. In cases where there are substan-
tial loads (from lights, refrigerators, radios, depth sounders, etc.),
it is essential to have a complete, separate system and to provide
charging current for this by means of a second alternator or
"alternator output splitter".
Starter batteries must be of a type which permits a high rate of
discharge (Diesel starting).
Carefully follow the recommended wire sizes shown in the wiring
diagrams. Plan installation so the battery is close to the engine and
use the following cable sizes:
#1 for distances up to 8 feet
#1/0 for distances up to 10 feet
#2/0 for distances up to 13 feet
#3/0 for distances up to 16 feet
MECHANICAL CONTROLS
The recommended practice is to have the stop-run lever loaded to
the run posi tion and controlled by a sheathed cable to a push-pull
knob at the pilot station. The throttle lever should be connected to
a Morse type lever at the pilot station by a sheathed cable.
The transmission control lever may be connected to the pilot sta-
tion by a flexible, sheathed cable and controlled by a Morse type
lever. The single-lever type gives clutch and throttle control with
full throttle range in neutral position. The two-lever type provides
clutch control with one lever and throttle control with the other.
Any bends in the control cables should be gradual. End sections
