PROPULSION SECTION 5
Propulsion
Your boat can be equipped with several types of inboard engine packages. 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 operate and maintain them, refer to the
OEM information.
Fuel Systems
Your boat’s propulsion engines use either a gasoline or diesel fuel system. The
major components used by each system are explained below.
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 port 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.
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 port fuel tank.
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. Turn the accessory battery master disconnect switch to the “ON” position.
2. On the Bridge Breaker Panel, switch the System DC Main circuit breaker
“ON,” then switch the Fuel Transfer Pump circuit breaker “ON.”
3. Check the fuel gauges at the helm. Identify the fuel tank that has the highest
fuel level.
4. Turn the fuel transfer switch, located at the helm, to the fuel tank to which
you want the fuel to flow.
5. Monitor the fuel gauges as the fuel transfers. When the fuel levels in the tanks
are equal, turn the fuel transfer switch to the “OFF” position.
6. On the Bridge Breaker Panel, switch the Fuel Transfer Pump circuit
breaker “OFF.”
