d. Cutlass Bearing
The cutlass bearing is mounted in a bronze casting which is designed to allow full flow of
water throughout the length of the bearing. This is important because the cutlass is water
lubricated.
A cutlass bearing should last several years. When the bearing is new, the shaft will be tight
and no lateral movement will be apparent when trying to push the shaft side to side. As the
bearing wears, one can move the shaft slightly from side to side or up and down. Once that
lateral movement is more than about 1/16 inch, the bearing should be changed. This may be
caused by engine mount failure.
Changing the bearing is a major maintenance job and might be best left to the professional
yacht mechanic. It requires that the boat be hauled. The shaft must be removed by loosening
the coupling set screws and pulling the shaft back through the gland. The four nuts on the
bearings’ casting retaining bolts are removed. The casting itself is threaded to the shaft log.
Therefore, one must screw the shaft log out from the casting. Once the casting is removed, it
is a simple matter to drive out the cutlass. It is not always necessary to remove the cutlass
bearing casting. After the shaft is removed, the bearing can sometimes be drawn from the
casting. One technique is to saw a small section out of the bearing so that it can be
compressed and drawn. One must use an unframed hacksaw and be careful to saw only the
bearing.
F. Electrical Systems
As mentioned in Section IV, the Tayana 42 has two standard electrical systems , a 12 volt DC
system that gets its power from batteries and the engine alternator, and a 110 volt AC system that
is powered through the shore power cable or with an outboard generator.
1. The 12 Volt DC System
The primary source of 12 volt power is the battery bank that comes with the yacht. The
battery(s) are used both to start the engine and to provide the various electrical equipment on
the yacht with power. The battery(s) are charged by the engine-mounted alternator or by a
battery charger (converter) that is connected to a 110 volt power source. Cruising yachts may
also use wind driven DC generators as well as solar cell panels to keep the house batteries
charged without running the engine.
Battery maintenance is simple, but demanding. You should check your battery water at
least once a month whether you have sailed the yacht or not. This is particularly important if
you have a 110 volt converter or battery charger in operation. The electrolyte (acid) level
should be maintained to cover the plates in the battery. It is best to use distilled water in your
battery(s), but that is not totally necessary. Clean, drinkable water can be used, if distilled
water is not available, but never use salt water. Excessive need of water is an indication that
the charging rate is too high. A check of the charging voltage should not read over 15 volts.
Should you spill electrolyte from the battery, it should be neutralized with baking soda.
