FEATURES & CONTROLS

Power Trim

Outboard position can be adjusted by pressing trim switch.
This range is used while operating your boat on plane.
•
Pressing (DN): Moves the outboard in closer to the boat transom,
called trimming "in" or "down."
•
Pressing (UP): Moves the outboard further away from the boat
transom, called trimming "out" or "up."
The term "trim":
•
Generally refers to the adjustment of the outboard within the first
°
20 range of travel.
POWER TRIM OPERATION
With most boats, operating around the middle of the "trim" range will
give satisfactory results. Trimming your outboard all the way in or out
may improve performance but cause some potential control haz-
ards.
Avoid possible serious injury or death. When the outboard is
trimmed in or out beyond a neutral steering condition, a pull
on the steering wheel in either direction may result. Failure to
keep a continuous firm grip on the steering wheel when this
condition exists can result in loss of boat control as the out-
board can turn freely. The boat can now "spin out" or go into
a very tight maximum turn which, if unexpected, can result in
occupants being thrown within the boat or out of the boat.
Consider the following lists carefully.
Trimming In or Down Can:
•
Lower the bow of the boat.
•
Result in quicker planing off.
•
Generally improve the ride in choppy water.
•
Increase steering torque or pull to the right (with the normal right
hand rotation propeller).
•
In excess, lower the bow to a point at which the boat begins to
plow with the bow in the water while on plane. This can result in
an unexpected turn in either direction called "bow steering" or
"over steering" if any turn is attempted, or if a significant wave is
encountered.
