ADJUSTMENTS
Trim Sending Unit Adjustment
(75 – 90 HP)
Tilt the outboard and engage the tilt support.
Temporarily install a thrust rod, P/N 436541, in the
number 3 hole.
Loosen the sending unit screws, to allow the
sending unit to pivot.
Disengage the tilt support. Lower the outboard
against the thrust rod.
Observe the trim gauge. If the needle does not
show center position, tilt the outboard up and
adjust the sending unit by pivoting it up or down.
Lower the outboard against the thrust rod to check
adjustment. Repeat adjustment, if necessary.
After adjustment is correct, tilt the outboard up,
tighten the two sending unit screws, and remove
the thrust rod.
Trim Limiter Rod
The trim limiter rod prevents excessive trim down.
As the engine is trimmed to the full down position,
the bow of the boat goes deeper into the water.
• If the trim limiter rod is left out, the bow could
plow into the water causing the boat to “bow
steer” resulting in a loss of control.
• If the trim limiter rod is set too far out, the pro-
peller could ventilate, resulting in poor accelera-
tion when the boat is coming onto plane.
Set the trim limiter rod to prevent excessive trim
down and provide good acceleration. The trim lim-
iter rod can be used to prevent the gearcase or
spray deflector from contacting the transom.

A WARNING
When the outboard is returned to the cus-
tomer, the trim limiter rod must be
installed and in the same location as it
was when the motor was brought in for
service. Leaving the trim limiter rod out, or
changing the adjustment, could allow the
motor to unexpectedly trim in too far and
cause loss of control.
