Propeller Information
Under no circumstance use a propeller which allows
the engine to operate at a higher than recommended
RPM.
NOTICE
NOTICE
It is advised that you always carry a spare propeller,
propeller hardware and propeller wrench on board.
Should your propeller become damaged it can be eas-
ily replaced.
Disconnect power by moving the battery switch to the
“OFF” position prior to removing the propeller.
DANGER
The engine(s) on the 240 Outrage
have been equipped with propellers
which our tests have shown to be
best suited for general use under nor-
mal conditions and load. In some
situations you may wish to change the propellers to
give your boat slightly different performance char-
acteristics. Changing your boats running surface, such
as the addition of bottom paint will affect the type
and size of propeller required.
In general, changing to a lower pitch propeller will
increase acceleration and load pulling capability, with
a slight decrease in top end speed. If you choose to
change propellers, the type should be discussed with
your Boston Whaler® dealer.

All propellers are designed to provide maximum for-
ward thrust, so the reverse thrust of the propeller will
not be as efficient. The 240 Outrage that has been
equipped with dual engines have propellers that are
designed to counter-rotate, which means that the port
engine’s propeller rotates the opposite direction of
the starboard engine. This will balance the torque
effects of the engine’s and along with the hydraulic
steering will reduce driver fatigue by eliminating the
constant need to fight the wheel.
