e “Bow Up” or out position is normally used for
cruising, running with a choppy wave condition,
or running at full speed. Excessive “bow up”
trim will cause propeller ventilation resulting in
propeller slippage. Use caution when operating
in rough water or crossing another boat’s wake.
Excessive “bow up” trim may result in the boat’s
bow rising rapidly, creating a hazardous condition.
Operation In “Bow Down” Position
e “Bow Down” or in position is normally used
for acceleration onto a plane, operating at slow
planning speeds, and running against a choppy
wave condition. It is also used when pulling water
skiers, tubers, knee boarders, etc. In this position
the boats’ bow will want to go deeper into the
water. If the boat is operated at high speed and/
or against high waves, the bow of the boat will
plow into the water.
Operation In “Level” Position
In normal running conditions, distribute
passengers and gear so boat is level. At or
below cruising speeds, trim the vessel for
optimum performance. The trim gauge will
show somewhere in the center of the gauge. is
position will also enhance running visibility and
overall stability. Again, each outing provides
di erent wave, load and running conditions. Make trim changes
as needed.
