INSTRUCTIONS AND WARRANTY.
Propeller
• It is advised that you always carry a spare
propeller, propeller hardware and propeller
wrench on board. Should your propeller
become damaged it can then be easily
replaced.
• Under no circumstance should you use a
p r o p e l l e r w h i c h a l l o w s t h e e n g i n e t o
operate at a higher than recommended RPM.
NOTICE
The engines on your 370 Outrage have been equipped
with propellers which our tests have shown to be best
suited for general use under normal conditions and
load. Your boat has been propped to achieve maximum
RPMs which meet Mercury requirements.
Trimming the Engines
When trimmed correctly, your boat will achieve
maximum RPMs, minimize steering effort, allow for
more stability and increased performance.
Trimming the engines IN full will drive the bow
down causing the boat to plow through the water and
will prevent the engines from achieving maximum
RPMs.
Trimming the engines OUT will push the stern down
and raise the bow. If OUT to far the maximim engine
RPMs cannot be achieved.
A properly trimmed boat will have the bow slightly
UP while running at full speed.
Different seas or operating conditions will necessitate
running the boat in different trim positions. The
operator will need to use his/her best judgement while
boating in different conditions.
Changing Propellers
In some situations you may wish to change the
propeller to give your boat slightly different
performance characteristics.
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 forward thrust,
consequently, the reverse thrust of the propeller will
not be as effi cient.
Propellers have two basic characteristics, diameter
and pitch.
Diameter is that distance measured across the
propeller hub from the outer edge of the 360
o
that
is made by the propeller’s blade during a single
rotation.
Pitch is that distance in inches that a propeller
will travel if rotated one revolution without any
slippage.
The zinc anodes generally need replacement once a
year in fresh water, every 6 months in a salt water
environment.
The need to replace anodes more frequently may
indicate a stray current problem within your boat or
at the slip or mooring. If your anodes do not need
replacement after one year, loose anodes or low-grade
zinc may be the problem.
Maintenance
The trim tabs are a completely sealed unit and are
waterproof and maintenance free.
Aside from a general cleaning when the boat is
out of the water you should also inspect the planes
and hinges for marine growth and remove as
neccessary.
