Trim “In” Angle Adjustment (Models
With Power Trim)
Some outboard boats, particularly some bass boats,
are built with a greater than normal transom angle
which will allow the outboard to be trimmed further “in”
or “under”. This greater trim “under” capability is de-
sirable to improve acceleration, reduce the angle and
time spend in a bow high boat attitude during planing
off, and in some cases, may be necessary to plane off
a boat with aft live wells, given the variety of available
propellers and height range of engine installations.
However, once on plane, the engine should be
trimmed to a more intermediate position to a avoid a
bow-down planing condition called “plowing”. Plow-
ing can cause “bow steering” or “over steering” and
inefficiently consumes horsepower. In this condition,
if attempting a turn or encountering a diagonal, mod-
erate wake, a more abrupt turn than intended may re-
sult.
In rare circumstances, the owner may decide to limit
the trim under. This can be accomplished by purchas-
ing a stainless steel tilt pin (P/N 17-49930A1) and in-
serting it through whatever pin hole is desired. The
non-stainless steel shipping bolt should not be used
in this application other than on a temporary basis.
IMPORTANT: Avoid possible serious injury or
death. Adjust outboard to an intermediate trim
position as soon as boat is on plane to avoid pos-
sible ejection due to boat spin-out. Do not at-
tempt to turn boat when on plane if outboard is
trimmed extremely in or down and there is a pull
on the steering wheel or tiller handle.

Checking Power Trim Fluid Level
1. Tilt outboard to the full up position and engage the
tilt support lever.
2. Remove fill cap and check fluid level. The fluid
level should be even with the bottom of the fill
hole. If necessary, add Quicksilver Power Trim &
Steering Fluid or automotive transmission fluid
(ATF) Type F, FA or Dexron II.

WARNING
DO NOT operate boat without the tilt pin installed.
Failure to install tilt pin could result in outboard
kicking up when operated in reverse causing se-
rious injury, death, or property damage.
Place tilt pin in desired hole in the transom bracket so
the outboard will run perpendicular to the water when
the boat is running at full speed. This allows the boat
to be driven parallel to the water.
