PROPULSION SYSTEM
This section discusses your boat’s propulsion equip-
ment. Proper maintenance of your engines will pro-
vide you with many hours of enjoyable, safe boating
and prevent unnecessary engine problems.
We strongly recommend that you become famil-
iar with all aspects of the engine’s proper opera-
tion as outlined in the Engine Operator’s Manual.
A general maintenance program consists of proper
lubrication and cleaning of fuel filters, fuel lines, and
air filters. Take precaution that water does not enter
the air inlets when the engines are not operating. This
will hep prevent water from entering into cylinders
and resulting in rust and internal engine damage.
The engines are warranted directly by Volvo Penta
and not by Chaparral.
Chaparral strongly recommends that you fully abide
by the Volvo Penta maintenance and warranty
schedule found in your Engine Operator’s Manual
included in the owner’s packet. Improper engine use
or maintenance may adversely affect the claims
made under the warranty provided by the engine
manufacturer.
Propellers
The propellers supplied with your boat have been
selected as the best propellers for typical use.
Consider keeping an extra set of propellers on your
boat. If the propellers become damaged, you can
replace them with the spares and continue your out-
ing. Check with your dealer if you want to purchase
an extra set.
Note: Under no circumstances should you use a
propeller that allows the engine to operate at
higher than maximum RPM for your engine.
