Trailering Outboard
WARNING
Excessive engine trim angle will result in insuffi-
cient water supply to water pump causing water
pump and/or powerhead overheating damage.
Make sure that water level is above gear housing
water intake holes whenever engine is running.
While operating “up” circuit, the cylinder rod will con-
tinue to tilt the outboard to a full up position for trailer-
ing.
Tilting Outboard Up and Down
Manually
WARNING
Before loosening the manual release valve, make
sure all persons are clear of engine as engine will
drop to full “down” position when valve is loos-
ened.
With power trim installed, the outboard can be raised
or lowered manually by opening the manual release
valve 3 to 4 turns (counterclockwise).

Trim “In” Angle Adjustment
WARNING
Operating some boats with engine trimmed to
the full “in” trim angle at planing speed will cause
undesirable and/or unsafe steering conditions.
Each boat must be water tested for handling
characteristics after engine installation and after
any trim adjustments.
IMPORTANT: Some boat/motor combinations
that are trimmed to the full “in” trim angle, will not
experience any undesirable and/or unsafe steer-
ing conditions during planing speed. However,
some boats with engine trimmed to the full “in”
trim angle at planing speed will cause undesir-
able and/or unsafe steering conditions. If these
steering conditions are experienced, adjust the
left and right tilt stop pins to prevent unsafe han-
dling characteristics.
Water test the boat. If undesirable and/or unsafe
steering conditions are experienced (boat runs with
nose down), adjust the left and right tilt stop pins in
proper hole to prevent unsafe handling characteris-
tics.
