The running angle can be controlled through the use
of power trim (stern drives) and/or trim tabs. See
Section E-8 - Trim Tabs and Section S-7 - Trimming
Your Boat for information on the use of trim tabs and
tilt/trim control switches (if applicable).
DO NOT operate the engine with the stern
drive tilted up. Severe damage to the engine
drive system can result. Consult the Engine
Owner’s manual for speciﬁc information.
E - 8 TRIM TABS
3 to 5
Electric/hydraulic trim tabs are standard equipment
and help provide maximum control of the hull in all
water and load conditions. If used properly, trim tabs
Compensate for wind and load listing
(level the boat side to side).
Induce faster planing and help achieve
optimum running angle (see Section E-7 -
Running Angle & Power Trim/Tilt).
The proper use of electric/hydraulic trim tabs requires
a basic understanding of trim tab operation and some
practice in calm water. Be sure to read the manufac-
turer’s literature included in the owner’s packet.
Figure E7: Running Angle
The trim tab control uses two (2) momentary-type
rocker switches. The trim tab switches control the
attitude or position of the boat. The trim tab switches
are labeled by position such as “Bow Up” and “Bow
Down”. They are also labeled for “Port” and “Stbd”.
When pressed, the label indicates what happens to
the bow of the boat.
A. Power Trim
Trim angle is how far in or out, the lower unit is
positioned in relation to the bottom of the boat.
The trim angle of the lower unit has a distinct affect
on the running angle of the boat.
Before leaving the dock and utilizing the trim tabs,
ensure the trim tabs are in the full up position. Press
both lower halves of the trim tab switches and hold
(for approximately 10 seconds) until the tabs are
The power trim system permits control of the trim
angle of the drive unit relative to the boat, at the touch
of a button.
It allows the drive unit to be raised (trimmed out) for
shallow water operation. Power trim also allows the
operator to adjust the drive unit while under way to
provide the ideal running angle for a given load and
water condition. Additional information can be found
in the engine owner’s manual.
A. Control Listing
Wind, loading and many other factors can result in
the boat tilting or leaning towards one side while
running. This is called listing and can be negated
using trim tabs.
B. Power Tilt
Power tilt allows the operator to raise and lower
the drive unit for trailering, launching, and beaching.
Additional information on power tilt can be found in
the engine manufacturer’s manual included with this
Pressing the lower port trim tab switch will move the
starboard trim tab upward. This will result in the port
bow of the boat being allowed to rise.
