• While using the boat, use the voltmeters to frequently monitor the
voltage level of each battery or battery bank. Monitor the charge
level with the engines turned off (static condition). Use the onboard
battery charger or the engine alternators to recharge the batteries
when they are not fully charged. Refer to 2.1.5 Charging the Bat-
teries for more information. When the battery bank is fully charged,
the voltmeter reads between 12.3 and 12.6 volts.
• Do not store batteries that are only partially charged. Recharge each
battery, if necessary. Check the voltage level every 30 days while the
battery is in storage and recharge it if the voltage reads below 12.3
volts.
• Do not charge the batteries if they are already fully charged. The
engine alternators can not overcharge the batteries. The onboard
battery charger can overcharge the batteries because, when it deter-
mines the batteries are fully charged, it does not shut off but rather
switches to trickle charge mode. Trickle charging a fully charged
battery reduces its useful life.
Disconnect the batteries when performing maintenance tasks on the DC
electrical system. Failure to do so can lead to electrical shock.
Inspect the batteries once every month. Clean any corrosion that has
developed on the battery terminals. Spray a terminal protector on the
terminals and battery cable eye connectors. Make sure the battery cables
are securely fastened to the terminals. Tighten the nuts only slightly
beyond finger tight with a wrench.
Check the level of fluid in each battery cell. Fill any low cells with dis-
tilled water only. The fill level is marked on the side of the battery case.
Spray the connections for the bridge instruments and switches with an
electrical connection protector every six months.
7.4.7 Fresh Water System
Flush and sanitize the fresh water system at least once every season.
Flushing involves draining all water from the system. Sanitizing involves
using a commercially-made fresh water tank sanitizing liquid that is
available at many marine supply stores.
7.4.7.1 Shower
If the water flow from a shower head becomes restricted, it may be due to
the accumulation of sediment in the shower head. If this happens, re-
