ends of the cutlass bearing. If worn, replacement is necessary. Propeller shafts must be
perfectly straight. Bent shafts can cause vibrations, misalignment, excessive stuffing
box leakage, wear of the cutlass bearing and extensive engine damage. (Refer also to
Section 30:03) The shaft is 1" in diameter with a 1/4" key and standard taper except for
Sabre 28's with the Atomic Four engine which has a 7/8" diameter shaft.
It is advisable to lock the propeller shaft while sailing by leaving the engine in gear
when shut off. With solid propellers, it is felt that the least amount of drag will occur
when the blades are locked in a position which has them in line with the strut. This can
best be done be adjusting the propeller to such a position on land by turning it with the
engine in neutral. Mark with paint a point on the shaft coupling

adjacent to a reference point on the engine. The propeller can then be moved to this
position and locked in place by putting the engine in gear. Volvo engines should be left
in forward and Westerbeke engines should be left in reverse when sailing. (Refer also to
Section 16:10)
With folding propeller, the preferred position is with the blades vertical when closed.
This will prevent a blade from hanging open since they are designed to close by the force
of water under sail, while in the horizontal position.
18:00 FUEL SYSTEM
Great care has been taken in the selection and installation of parts related to the fuel
system. Caution is advised during any procedure affecting this system in order to
maintain the integrity of the safety built­in. (Refer to I­17)
18:01 DECK FILL PLATE: A deck fill plate and cover are mounted flush with the deck.
Use only the spanner wrench provided to remove or install the cover.
18:02 FUEL TANK: The aluminum fuel tank is vented through a flexible rubber hose that
extends from the top of the tank to a screened vent at the stern. The screen should be
checked periodically for insects or debris with could obstruct venting and therefor
prevent the flow of fuel.
The fuel lift pump has a capacity in excess of that required by the injector pump. The
overflow is piped back into the fuel tank.
The deck fill plate, fuel tank and engine are all connected to the grounding system.
(Refer to Section 22:00 for further information)
18:03 SHUT OFF VALVE: A fuel shut off valve is located on the side of the galley
facing the quarter berth. The handle is vertical when open and horizontal when closed.
Keep this valve closed at all times when the engine is not in use.
18:04 FUEL FILTERS: A dependable supply of clean diesel fuel is necessary to insure
satisfactory operation of the engine. Cleanliness and care are important to all aspects of
the fuel system and special care against contamination during fueling should be used.
A primary fuel filter is mounted in the engine compartment which separates water from the
fuel through centrifugal and gravitational force. Foreign particles are trapped in a
replaceable filter element. The element should be checked periodically and requires
changing a minimum of once per season. A glass bowl on the bottom of the filter allows
easy inspection for the presence of water. Any water can be removed by opening the
petcock on the bottom, as the water is denser than fuel.
A secondary fuel filter is fitted on the engine between the fuel lift pump and the
injector pump, also containing an element which should be replaced each season. Refer to
the engine owner's manual for further details.
