When running at an engine speed that results in the boat
falling off plane or causes the boat to plane inefficiently,
lowering both tabs slightly (bow down) will improve the
running angle and improve operating efficiency.
Optimum efficiency is obtained when operating at a 3 to
5
degree running angle. Utilizing too much “Bow Down”

tab positioning, raise the trim tabs to the full-up position.

When running at high engine speeds, be sure
the trim tabs are in the full up position. Trim tab
