5.0 Propulsion
Your boat can be equipped with several types of inboard engine packages.
This section gives a general overview of your propulsion system and how it
works. For a detailed explanation of the engines installed in your boat,
including how to operate and maintain them, refer to the OEM information.
5.1 Fuel System
Each diesel propulsion engine in your boat is plumbed to the fuel tank
located on the same side of the boat as the engine. The diesel propulsion
system uses fuel supply and return lines. The supply lines feed fuel to the
engine; the return lines transfer fuel not burned by the engine back to the
fuel tank. The generator draws fuel from the starboard fuel tank only.
5.1.1 Fuel Tanks
Your boat holds a maximum 560 gallons of fuel in two tanks. The fuel tanks
are located on the starboard and port sides of the aft bilge area. The fuel
system meets or exceeds the standards set by the U.S. Coast Guard, the
Boating Industry Association, and the American Boat and Yacht Council
that were in effect when your boat was constructed. Each fuel tank has
passed a rigorous test conducted by the tank manufacturer. Additionally,
the entire fuel system passed Carver’s own pressure testing and inspection.
Before your boat is delivered, your Carver Dealer also makes a full inspec-
tion of the fuel system. An entry on the Carver Pre-Delivery Service Record
verifies the dealer’s completion of this inspection.
5.1.2 Fuel Equalization Valves
Because the generator draws fuel only from the starboard fuel tank, the fuel
levels in the tanks may become unequal. If this occurs, open the fuel equal-
ization valves, located on the bottom near the aft center of each tank. When
the fuel levels are equal, close the valves.
Always close both fuel equalization valves when you are not equalizing
the fuel levels in the fuel tanks. If one of the valves developed a leak while
open and unattended, fuel could spill into the engine room undetected,
creating a hazardous condition.
5.1.3 Fuel Shut-Off Valves
Fuel shut-off valves are installed between the fuel lines, both supply and
return, and the fuel tank that they are connected to. The valves are located
on top of the fuel tanks and must be open when operating the engines.
