OUTBOARD INSTALLATION
113
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.

Limits the down trim angle of the
power trim equipped engines, or
aids in determining the trim out
angle on non‑power trim engines.
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.
