Operation
Power Trim while running
The Power Trim adjusts the drive angle to the stern of
the boat to obtain maximum comfort and fuel economy
at different speeds, with varying loads, and in a range
of wind and sea conditions.
Power Trim settings and adjustment are controlled
from the helm position using the controls and instru-
ments described in the Power Trim chapter.
WARNING!
Avoid over-trimming the drive system
as this can adversely effect the steering of the
boat severely.
The engine must not be run with the drive in the
“Lift” range.
IMPORTANT!
Avoid running with the drive fully
trimmed for long periods (when planing). Apart
from excessive fuel consumption this can cause
cavity damage to the propeller(s).
Operating with the drive in the Trim range
The Trim range is used to achieve maximum comfort
under normal operation at all speeds from start to maxi-
mum speed.
Since every boat has its own unique characteristics
and will be effected in different ways by the factors in-
volved, only general advice is given here on how to get
the best trimming angle for your boat. It can generally
be said that when the boat feels well-balanced, easy to
steer and pleasant to operate, then that is the optimal
trim angle for the boat.
When starting
Trim the drive down. The bow will be pressed down and
the boat accelerates faster. This gives improved run-
ning and steering characteristics at speeds below the
planing threshold.
At planing speed
Trim the drive out to the operating position which pro-
vides the most stable and comfortable running.
If the boat has twin motors the drives can be trimmed
with different angles to compensate for side winds and
to a certain extent compensate for uneven loading on
one side of the boat or the other.
