Shallow Water / Hole Shot
To lift the stern and lower the bow, lower both tabs completely down by pressing
BOW DOWN on both tabs. As you throttle up and speed increases, raise the tabs
by pressing BOW UP on both tabs.
Porpoising
Porpoising is a condition more common in faster boats. As speed increases, the
bow repeatedly rises out of the water until gravity overcomes lift and the bow
falls down. Press "Bow Down" in half second bursts. As the trim tabs deflect, the
porpoising subsides and your speed should remain the same or decrease. Only a
slight amount of trim tab deflection should be necessary.
Safety Precautions
Bennett trim tabs have a significant effect on the operation and versatility of your
boat. No one knows your boat better than you, so the best learning method is to
spend time getting familiar with your boat's reaction to the trim tabs. Remember,
practice makes perfect! As your experience increases, so will your enjoyment.
Always operate your boat with safety first in mind.
• Do not over-trim, particularly at high speeds as the bow will dig in and wave
action may cause the boat to veer.
• While operating trim tabs, use caution. Improper use of trim tabs may cause
accidents and/or injury.
• For best maneuverability, trim tabs should be fully retracted in a following sea,
or when running in an inlet.
