5.0 Propulsion
Your boat can be equipped with several types of inboard engine pack-
ages. The engines may be gas or diesel. 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 oper-
ate and maintain them, refer to the OEM information.
5.1 Fuel Systems
Your boat’s propulsion engines use either a gasoline or diesel fuel sys-
tem. The major components used by each system are explained below.
5.1.1 Gasoline Fuel Systems
Each gasoline propulsion engine in your boat is plumbed to the fuel tank
located on the same side of the boat as the engine. The generator draws
fuel from the starboard fuel tank.
Anti-siphon check valves are installed in gasoline fuel systems between
the fuel hose and the fuel tank withdrawal tube. These check valves
automatically stop the flow of fuel if the fuel hose ruptures or becomes
disconnected.
Never remove an anti-siphon check valve from the fuel system. The
valves are important safety components. Clean or replace obstructed or
sticking valves.
5.1.2 Diesel Fuel Systems
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.
5.1.2.1 Fuel Transfer Pump
A fuel transfer pump is included with the diesel fuel system. Because the
generator draws fuel only from the port fuel tank, the fuel levels in the
tanks may become unequal. If this occurs, use the fuel transfer pump to
pump fuel from one tank to the other until the fuel levels are equal.
To transfer fuel between fuel tanks:
1. Open the fuel transfer line valves. These valves are located on the
bottom of the fuel tanks near the aft inboard corner.
