Tuning For Optimal Performance

There are four main features which can be adjusted on your Impulse 32 boat to tune it for optimal performance. Tuning is a
balance of these settings; making a change to any of these settings may require you to adjust other settings elsewhere. It is
normal and highly recommended to tune your boat for the boating conditions for the best performance every time you take your
boat out. When water conditions change, as a result you should make changes to fine tune your boat to the new conditions.
Getting accustomed to tuning your boat on a regular basis will help you achieve the best boating experience. Finding the proper
tuning settings will reduce the chance of a blow over and/or porpoising.
Prop Angle Adjustment
• Raising the prop strut increases speed, but also
increases porpoising risk, and increases cavitation. Raise
the prop strut to keep the nose of the boat riding high in
rough water. If the strut is too high the boat will begin
to loose stability and turn precision at higher speeds.
• Lowering the drive strut increases steering stability,
but also increases drag and decreases speed. Lower
the prop strut for smooth water conditions. If the strut
is too low it will increase turn stability and authority,
but will increase drag, and reduce speed.
1. Loosen nut and bolt securing the drive strut on the rear
of the boat.
2. Slide the strut up or down to change the angle of the
propeller in relation to the hull.
3. Adjust as desired and tighten the nut and bolt.
Battery Placement
• For rough water move the batteries toward the back of the boat.
• In smooth water you can move the batteries forward more to
gain speed.
• Move the batteries forward if the boat wants to porpoise.
Trim Tabs
• In smooth water conditions, lowing the trim tabs can
help balance the ride of the boat by maximizing the
prop strut to gain speed, while the trim tabs help keep
the nose of the boat lower.
• In rough water, raise the trim tabs to help keep the
bow of the boat riding high.
• Trim tabs are used to give your boat a flat riding stance
when at speed. If your boat is leaning to one side
simply increase the depth of the trim tab on the side
that is deeper in the water to balance the boat laterally.
1. Loosen the nut securing the trim tab setting.
2. Adjust the bolt to hold the trim tab at the desired angle.
3. Tighten the nut to prevent the bolt from moving.
Turn Fins
• In smooth water conditions and for high speed
performance, raise the turn fins to increase speed.
• In rough water and for more turning authority, lower
the turn fins.
1. Loosen nut and bolt securing turn fin.
2. Tighten the nut and bolt while holding the turn fin at the
desired angle.
