4. Secure propeller nut by bending three of the tabs into the thrust hub grooves.

Trim In Pin

Avoid possible serious injury or death. Adjust outboard to an intermediate trim position
as soon as boat is on plane to avoid possible ejection due to boat spin out. Do not
attempt to turn boat when on plane if outboard is trimmed extremely in or down and
there is a pull on the steering wheel.
Some 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 desirable to improve acceleration, reduce the angle and time spent in
a bow high boat 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 avoid a bow-down planing condition called plowing. Plowing can cause bow steering
or over steering and inefficiently consumes horsepower.
Stainless Steel Tilt Pin
The owner may decide to limit the trim in. This can be accomplished by purchasing a
stainless steel tilt pin from your dealer and insert it in whatever adjustment hole in the
transom brackets is desired. A non-stainless steel shipping bolt should not be used in this
application other than on a temporary basis.
