Chaparral 420 PREMIERE, Owner'S/Operator'S Manual

Page: 139 / 164

Routine inspection, service and maintenance of
your boat’s systems are the key to trouble-free oper-
ation, as well as for prolonging the life of your boat.
Do not attempt any repairs on your boat unless you
are qualified to do so.
Only use approved marine replacement parts avail-
able from your Chaparral dealer. Chaparral recom-
mends that you have an authorized Chaparral deal-
er do your maintenance and repair work. Your deal-
er is qualified to make repairs or modifications to
your boat in such a manner as to not compromise
safety, design integrity, or warranty coverage. This
chapter includes information you can use to do gen-
eral maintenance and repair, and descriptions of
convenient methods for evaluating the condition of
some of your boat’s systems.
Develop regular routines for inspecting your boat.
The chart below summarizes inspection, service
and maintenance activities. The interval between
necessary service and maintenance is highly vari-
able, and depends on the environment your boat is
in and on the severity of operating conditions. For
example, the corrosion of parts on boats operated in
salt water proceeds much faster than the corrosion
of parts on a boat operated in fresh water. The inter-
vals listed below are recommended maximums, and
you must reduce the time between inspections if
your observations indicate such a need.
