FUEL PIPING
We recommend copper tubing together with suitable fittings, both 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 engine 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 engine 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 engine should be through flexible rubber hoses.
ELECTRIC PANEL
The Westerbeke all-electric panel utilizes an electronic tachometer with a built-in hour meter.
Tachometer cables are no longer required, except for the Skipper mechanical panel. Mounted on the
panel are a voltmeter, water temperature gauge and oil 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 Westerbeke engines are supplied pre-wired and with 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 requirements. 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 substantial 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 position 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.
