OUTBOARD INSTALLATION

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.

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 oversteering and

inefficiently consumes horsepower.
