Section 3 • Systems & Components Overview & Operation
R
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
propeller which allows the engine to
operate at a higher than recommended RPM.
NOTICE
The engines on your 345 Conquest 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 maximum 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.
Although you will most likely keep your Auto Glide
in automatic mode, you may convert to manual mode
simply by pressing one of the four up/down buttons
on the key pad.

If equipped, the
Active trim panel
is located on the
forward hardtop
above the console.
A c t i v e T r i m
provides the benefit of perfect trimming without
constantly monitoring and adjusting trim with
changes to boat speed or when going into turns.
Active Trim controls the trim in accordance with
boat speed and engine rpm. This avoids potential
problems such as engines trimming up (instead of
down) if the propeller breaks loose in a hard turn. It
also avoids issues with the engine trimming up too
early or too late when the boat is getting on plane.
Active Trim has five selectable trim profiles that
accommodate nearly any boat application. These
profiles allow operators to compensate for changes
in boat load, operator preference and weather
conditions, while maintaining full auto operation.

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 efficient.

DANGER
Disconnect power by moving the battery switch
to the “OFF” position prior to removing the
propeller.
