Hydraulic Up/Down Adjustment; Trim Pump Thermal Switch Operation - Mercury SST120 User Manual

FEATURES & CONTROLS

Hydraulic Up/Down Adjustment

Your outboard can be raised up and down approximately 1" (2.54 cm)
hydraulically. The hydraulic system allows the operator to raise or
lower the outboard while on plane.
HYDRAULIC UP/DOWN OPERATION
The optimum height adjustment for your boat will depend on many
variables such as water conditions, boat design, propeller size and
design, weight distribution, etc. During a race both water conditions
and fuel load could/will change which could greatly affect the opti-
mum height adjustment of your outboard. Care must be given to opti-
mize safe handling throughout a race or other operation of the boat
and to maintain adequate water supply to the engine at all times.
Avoid possible serious injury or death. Do not operate your
outboard at a height adjustment that could cause unsafe han-
dling conditions or a lack of cooling water to the engine. When
racing, extensive testing is necessary for the operator to be fa-
miliar with all aspects of the boats handling, which can be
greatly affected by the Up/Down adjustment.

Trim Pump Thermal Switch Operation

Release the trim switch as soon as the outboard reaches the end of
its travel or an overload switch will stop the pump motor operation.
If the overload switch should open, do not depress the trim switch for
approximately one minute. After this period of time, the overload
switch will reset itself and the pump may again be operated.
