the shaft between the packing nut and the stuffing box and slide the nut
back in place with the new packing. This procedure should only be
attempted with the boat out of water. Once launched, realign the shaft,
run the engine, checking the water flow again making any necessary
adjustments as described before.
A two bladed 13 x 11 RH bronze propeller is installed as standard with
the Westerbeke 13 marine diesel.
To remove the propeller, a special service tool must be used in order
not to distort the propeller or bend the shaft. A propeller puller
provides even force around the propeller when centered properly on the
shaft.
Remove the cotter pin, zinc and lock nut. A light tap with a block of
wood or rubber headed mallet should dislodge a stuck propeller when used
in conjunction with a propeller puller.
Before refitting the propel for, check the assembly parts for corrosion
or wear and replace if necessary.
The propeller shaft is made from solid bronze 1" diameter stock. Its
straightness conforms to the standards set up by ABYC as a guideline for
shafting. The taper conforms to SAE standards for propeller shafts and
is fitted with a 1/4" keyway, 2" long.
The shaft is supported by a cutless bearing within a fiberglass stern
tube in the aperture and a solid half coupling at the engine.
When painting the bottom of the boat, avoid painting the cutless bearing
as a flow of water is absolutely necessary around the shaft for good
lubrication at the cutless and the stuffing box. If these dry out, the
life of each is shortened and the shaft will overheat possibly causing
distortion which cannot be repaired.
By shifting the engine into reverse with the engine off and under sail,
you will prevent the propeller from "freewheeling" in neutral. This
"freewheeling" can cause excessive gear wear, overheating of the gear
box and noise if allowed to do so for long periods of time.
By locking the propeller vertically behind the forward end of the
aperture, you can decrease drag and protect your propeller from fouling.
Align the propeller with the keel and mark reference points on the
coupling and engine for a quick visual check for alignment.
FUEL SYSTEMS
The fuel system incorporates a 5052 aluminum alloy fuel tank and a
combination of flexible fuel lines and reinforced rubber hose. The fuel
fill deck plate is located on the starboard side deck adjacent to the
forward lower chainplate. It connects to the fuel tank via an 1-1/2" ID
U.S.C.G. rated fuel hose. Flexible fuel lines have been chosen as they
are very easily repaired in the field should a leak develop. Copper
fuel lines require special tools to repair which may not be available at
