4.4 Engine Power Tilt & Trim
All outboard engines are equipped with a tilt and
trim feature. On most outboard boats, tilt/trim
switches are built into the engine shift and throttle
controls that allow the operator to control the po-
sition of the outboards from the helm. Typically,
a switch or switches on the port control lever grip
activates the tilt/trim for all engines simultaneously.
Most Yamaha engine controls have three switches
for quad engines on the cover that activate each
engine tilt/trim individually.
Notice:
Some quad engine controls are equipped
with a separate tilt/trim switch panel with
a switch for each engine.
The maximum tilt angle is usually preset at the
factory. If necessary, the maximum tilt angle can
be adjusted by your Everglades or engine dealer
by reprogramming the settings using a computer
controlled diagnostic system.
Moving the outboards closer to the boat transom
is called trimming “in” or “down.” Moving the out
-
boards further away from the boat transom is called
trimming “out” or “up.” In most cases, the boat
will run best with the outboards 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 outboards within the first 20
0
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 outboards further up for
shallow water operation or trailering.
Some control systems provide a means to set the
engine trim angle to automatically adjust accord-
ing to the engine speed. For information on the
proper use and maintenance of the power tilt and
trim, refer to the engine owner’s manual.
CAUTION
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 PORT OR
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.
