WEIGHT DISTRIBUTION
Positioning of gear, passengers and extra ballast weight
inside the boat can have great e󰀨ects on the handling
and performance of your boat and engine:
Consult your dealer for advise on setting up weight
distribution in your model boat for the best handling and
performance for the particular activity you are trying to
do.
CONDITIONS AFFECTING OPERATION - 6
BOAT BOTTOM
To ensure maximum engine performance, fuel economy
and boat speed, the bottom of your boat must be kept
clean and free of marine growth and barnacles. Marine
vegetation may accumulate when the boat is docked
and should be removed before operation. If the boat
is docked for long periods of time, the water inlets may
become clogged with growth and will cause the engine
to overheat.
In most areas, it is advisable to coat the boat bottom
with antifouling paint to prevent the build-up of marine
growth. Contact your certied dealer for advice on these
requirements in your area.
PROPELLER SELECTION
Best all-around performance and maximum engine life is
achieved when the engine is propped to run near the top
of (but within) the recommended full throttle RPM range
with a normal load. See ENGINE SPECIFICATIONS for
rated full throttle RPM for your model engine.
Generally, gross weight (total weight of the entire
boat, including full fuel and water, optional equipment,
passengers and other miscellaneous gear) is one of
the major factors and should be one of the primary
considerations when selecting a propeller. Other factors
to take into consideration are as follows:
• Warmer weather and higher humidity will cause
an RPM loss.
• Operating the boat in a higher elevation will
cause an RPM loss.
• Operating the boat with an increased load will
cause an RPM loss (additional equipment,
passengers, etc.).
CAUTION
Prolonged WOT operation will shorten the life of
your engine and could cause premature engine
failure. See NORMAL CRUISING SPEEDS in
SPECIFICATIONS. Problems caused by prolonged
WOT operation are considered abuse and are not
covered under the Challenger Warranty.
If full throttle RPM is above or below the recommended
range as stated in ENGINE SPECIFICATIONS,
the propeller must be changed to prevent loss of
performance. A one-inch change in the pitch of a given
propeller will generally change engine RPM by 150 to
250 RPM.
IMPORTANT NOTICE: Your new Crusader
Challenger engine incorporates an RPM “MAX
GOVERNOR” in order to prevent the engine from
over-revving. Operation above the Maximum RPM
listed, in the chart above, is not recommended. If
your engine is operating above the maximum RPM
listed, a higher pitched propeller would be required
to lower the engine maximum RPM to the Preferred
RPM listed in the chart above.
