the remote control handle from neutral into forward gear 3–5 times. This

process.
Trim In Pin
!
WARNING
Operating the boat at high speeds with the outboard trimmed too far under
can create excessive bow steer, resulting in the operator losing control of the
boat. Install the trim limit pin in a position that prevents excessive trim under
and operate the boat in a safe manner.
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 livewells, given the variety
of available propellers and height range of engine installations.
