Power Trim System
General Information
The power trim system is filled at the manufacturer and is ready for use.
Trim outboard through entire trim and tilt range several times to remove any air from the sys-
tem.
The trim system is pressurized and is not externally vented.
Power Trim Operation
With most boats, operating around the middle of the “trim” range will give satisfactory re-
sults. However, to take full advantage of the trimming capability there may be times when
you choose to trim your outboard all the way in or out. Along with an improvement in some
performance aspects comes a greater responsibility for the operator, and this is being aware
of some potential control hazards. The most significant control hazard is a pull or “torque”
that can be felt on the steering wheel or tiller handle. This steering torque results from the
outboard being trimmed so that the propeller shaft is not parallel to the water surface.
