Chapter 4
Do not trim the engine out too far or the boat may begin to
"porpoise" (bounce up and down). Porpoising reduces control
and visibility.
To use power trim effectively, always start with the engine trimmed in. As
the boat planes, increase the angle out. Experience is the best teacher for
understanding proper trim.
