4.4 Engine Power Tilt & Trim
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. Engine controls typically have two
switches on the cover that activate each engine
tilt/trim individually. If necessary, the maximum
tilt angle can be adjusted by your Everglades or
engine dealer by reprogramming the settings using
the engine 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 rst 20
o
range of travel.
This is the range used while operating your boat on
plane. The term “tilt” is generally used when refer-
ring 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.
CONTINUED OPERATION OF AN IMPROPERLY TRIMMED
MOTOR COULD RESULT IN OVERHEATING AND POTENTIAL
FAILURE OF THE ENGINE.
THE 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.
