Sport Boat
When Underway
• Raise the trim tabs above the boat bottom.
• Increase speed. The bow will start to come down.
• When the bow begins to fall, trim the engine(s) out. Trimming the
engine(s) out at speed will cause the boat to rise up. The boat will begin
accelerating without adjusting the throttle because less of the boat is
dragging in the water. Steering will become easier because the
propeller has less torque.
• Watch the tachometer to keep the engine within the full throttle
operating range. See the engine operator’s manual for the proper
tachometer reading at full throttle.
High speed operation on smooth water is very stable, but quick reactions
and adjustments are needed to maintain control. Know your limits and stay
within them. Always keep one hand on the steering wheel and the other on
the throttle; constant adjustments are necessary for rapidly changing
conditions. Small inputs of throttle and steering are exaggerated at high
speeds. Depending on the speed, keep watch well ahead so that you may
have enough time to react.

 WARNING
Keep one hand on the wheel and the other on the throttle
controls at all times. If the boat begins to operate in an unsafe
way, pull back on the throttle and trim the engines IN at the
same time. Failure to maintain control could result in severe
injury or death.
 WARNING
DO NOT trim the engine out too far or the boat may begin to
“porpoise” (bounce up and down). Porpoising reduces control
and visibility and lowers top speed and fuel efficiency. Failure to
maintain control or visibility could result in serious injury or
death.
