MAINTENANCE SECTION 7
Propeller Shaft Seals
The propeller shaft extends through a watertight fitting called a shaft seal. Check
the shaft seal every month; if the seal is leaking, contact your Carver Dealer.
Make sure the engines are OFF before inspecting the propeller shaft
seals. The engine room contains moving, hot machinery. Keep your
hands, feet and body out of the engine room while one or both engines
are operating.
Props
Inspect your props often. Carry a swim mask in your boat so you can inspect the
props while swimming. Props that are out-of-balance or damaged can diminish
the boat’s performance by reducing the boat’s speed, causing steering problems,
and creating vibrations. Vibrations can lead to drive train damage.
Have the propellers balanced by an established propeller repair shop at least
once a year. Repair or replace damaged props.
Wear gloves when handling a propeller. Its blades are sharp.
Struts
Propeller shaft struts require very little maintenance. Within each strut is a strut
or cutlass bearing that provides a smooth surface for the shaft to rotate. These
bearings occasionally need to be replaced. They need replacement more often
if you use your boat in water that has a lot of sand or other abrasive material
suspended in it. Have a marine technician inspect the strut bearings whenever
the boat is pulled. Replace the bearings when the technician recommends it.
DC Electrical System
The majority of difficulties that occur with the 12-volt DC electrical system are
caused by poor battery maintenance. The factory-installed batteries on your boat
should function normally for several years if properly maintained. These heavy-
duty batteries can be discharged and recharged repeatedly without damaging
them; however, completely discharging or overcharging a battery can shorten its
life span.
To maximize the useful life of the batteries:
• 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
Section 2 - Charging the Batteries for more information. When the battery
bank is fully charged, the voltmeter reads between 12.3 and 12.6 volts.
A TIP FROM CARVER!
Consider purchasing and carrying a spare set of props onboard your boat. Many
marine dealers do not carry a full inventory of replacement propellers. A spare set
allows your vacation or cruise to continue in the event that your boat’s primary set of
props is damaged.
