shaft coupling inside the boat. The ground brush is then connected to the common ground
terminal on the keel with at least a #10 gauge stranded copper conductor.
23:00 UNDERWATER CORROSION (Cont'd)
23:04 ELECTRICAL SWITCHES: Electrical switches and hardware should be checked to
assure that they are operating properly. An ohmmeter can be used to check that all
switches are opening and closing properly. A switch that does not shut off completely can
easily cause a stray current.
The following switches and hardware should be checked for proper operation:
­ Main battery switch
­ Engine key switch
­ Blower switch
­ All 12 volt DC panel switches
­ 100 volt AC panel switches and accessories
­ Battery charge indicator
­ Float switches for bilge and sump pumps
Note: Reverse polarity at bilge pump wiring is a common cause of stray current corrosion.
Any wiring connections made in bilge water or wet locations should be waterproofed with
heat shrink tubing.
23:05 EXTERNAL FACTORS: External as well as internal factors can also contribute to
corrosion of underwater hardware. Some of the more common external sources include water
velocity and turbulence, polluted water, electrical leaks at shore power installations,
improper use of portable battery chargers and electrical leaks from adjacent boats.
24:00 FRESH WATER SYSTEM
Plumbing in Sabre yachts meets or exceeds marine standards and utilizes FDA approved and
corrosion resistant material throughout.
24:01 WATER TANK: The water tank has a flush mounted deck fill plate. To remove or
install the fill cover, always use the spanner wrench provided. Use caution when filling
the water tank to insure that the tank is not over filled. Excessive pressure results if
water is allowed to fill the fill pipe which may be damaging to the system. Gravity feed
only.
A wide mouth access cover is removable for inspection and clean out of the system. Water
left in a tank for a long period of time will become stale. Tanks should be pumped out
if this occurs, and cleaned with a baking soda and water solution followed by rinsing with
fresh water.
Failure of pump to pump water may be due to a clogged water filter located either internal
or external of tank.
24:02 VENT: The fresh water tank is vented forward into the anchor well. This
protects from saltwater contamination when the boat heels over.
24:03 LEAKS: If the water storage tank appears to be leaking, check that the water
inlet hose is secure and dry at the deck fitting and at the tank. Also check the vent
line and outlet hose at their connections. Leaks here or at other fitting locations may
be overcome be refitting and tightening the hose clamps.
24:04 PRESSURIZED WATER SYSTEMS: Boats with pressurized water systems have on­off
valves at the mouth of the foot pump faucet. The valve is opened by turning it to the
