Helm Control Systems
Notice:
Some outboard control systems are equipped
with a computer controlled start feature that
will keep the starter engaged until the engine
starts if the neutral safety switch fails and al-
lows the starter to engage.
The starter should not engage for any engine. Re-
peat this test with the shift levers in reverse and the
engine throttles at idle. Again, the starter should not
engage for any engine. If the starter for any engine
engages with the shift controls in any position other
than the neutral position, then the neutral safety
switch is not functioning properly and you should
contact your dealer to have the neutral safety switch
repaired by a qualified marine mechanic before
using the boat. If an engine starts in gear during
this test, immediately move the control lever to the
neutral position and turn the engine off.
WARNING
IN SOME SITUATIONS, IT MAY BE POSSIBLE TO
ACCIDENTALLY START THE ENGINES IN GEAR WITH
THE THROTTLES ABOVE IDLE IF THE NEUTRAL SAFETY
SWITCH IS NOT OPERATING PROPERLY. THIS WOULD
CAUSE THE BOAT TO ACCELERATE UNEXPECTEDLY IN
FORWARD OR REVERSE AND COULD RESULT IN LOSS
OF CONTROL, DAMAGE TO THE BOAT OR INJURY TO
PASSENGERS. ALWAYS TEST THE NEUTRAL SAFETY
SWITCH PERIODICALLY AND CORRECT ANY PROBLEMS
BEFORE USING THE BOAT.
4.4 Engine Power Tilt & Trim
All outboard engines have a tilt and trim feature.
Most outboard engines have tilt/trim switches built
into the engine shift and throttle controls that allow
the operator to control the position of the outboards
from the helm. Typically, a switch or switches on the
port control lever grip activates the tilt/trim for the
engines. Twin engine controls have two switches
on the cover that activate each engine tilt/trim
individually. If necessary, the maximum tilt angle
can be adjusted by your Crevalle or engine dealer
by reprogramming the settings using the engine
manufacturer’s diagnostic system.
Moving the outboard closer to the boat transom is
called trimming “in” or “down.” Moving the outboard
further away from the boat transom is called trim-
ming “out” or “up.” In most cases, the boat will run
best with the outboard adjusted so the hull will run
at a 3 to 5 degree angle to the water.
The term “trim” generally refers to the adjustment
of the outboard within the first 20
o
range of travel.
This is the range used while operating your boat
on plane. The term “tilt” is generally used when
referring to adjusting the outboard further up
for shallow water operation or trailering. For
information on the proper use and maintenance of
the power tilt and trim, refer to the engine owner’s
manual.
CAUTION
ENGINE HOSES AND CABLES OR THE TRANSOM GEL
COAT CAN BE DAMAGED BY TILTING THE ENGINES TO THE
FULL UP POSITION WITH THE ENGINES TURNED TO THE
WRONG POSITION. MOST BOATS REQUIRE THE STEERING
WHEEL TO BE TURNED COMPLETELY TO STARBOARD
BEFORE TILTING THE ENGINES TO THE FULL UP POSITION.
YOU SHOULD MONITOR EACH ENGINE AS IT TILTS TO
DETERMINE BEST FULL TILT ENGINE POSITION FOR YOUR
BOAT.
