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 WOT
operation are considered abuse and are not covered
under the Crusader Warranty.
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.).
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 either the pitch
or diameter of a given propeller will generally change
engine RPM by 150 to 250 RPM.
NOTICE: These engines incorporate an RPM “REV
LIMIT” in order to prevent the engine from over-revving.
