Checking The Radio System; Handling Adjustment - Pro Boat Impulse 26 Owner's Manual

Checking the Radio System

1. Center the throttle and steering trims on the transmitter.
2. Turn the transmitter on.
3. Connect the fully charged battery pack(s) to the ESC.
4. Power on the ESC.
5. Confirm proper rudder direction as shown.
6. Throttle Test (Impulse 31):
a. The ESC will beep until you give full throttle input.
b. Move the throttle to full throttle. The ESC will stop beeping.
c. Return the throttle to neutral.
d. Move the throttle a small amount. The prop will turn.
Brushless boats have an over-rev limiter that will not allow you to
hold full throttle when the propeller is not loaded (out of the water).
To reset, return the throttle trigger to neutral. The auto sensing
voltage cutoff will also cut off power to the motor when the
ESC senses that the batteries are nearing full discharge.
7. Disconnect batteries from the ESC and power off the transmitter
until you are ready to run your boat.
8. Install the radio box cover and hatch.
NOTICE: Always turn the transmitter on before connecting
battery packs to the ESC. Never transport the boat with
the battery packs connected to the ESC.
WARNINg: Always stay clear of the propeller.

Handling Adjustment

Impulse 26
Trim Tabs
The trim tabs can greatly enhance the
performance of your Impulse 26. To adjust
the angle of the trim tabs, use a large pair
of pliers to carefully bend the tabs as shown.
This must be done carefully so that you do
not damage the transom. If you would like
a calmer, more controlled run, carefully bend
the tabs down 1⁄8-inch. If your goal is to go
faster and to add excitement, bend the tabs up.
Wake Conditions
It is advisable to run your Impulse 26 in low to medium wake conditions
to avoid having problems with the boat overturning. If the conditions are
questionable, bend the trim tabs down a bit to reduce the likelihood of
having the boat overturn.
Impulse 31
Operate your boat in low to medium wake conditions to avoid having
problems with the boat overturning.
Center of gravity
Moving the batteries to the front or back can significantly affect the
boat's performance.
a. Move the batteries toward the rear of the boat to raise the front
of the hull out of the water for increased speed.
b. Move the batteries toward the front of the boat for faster initial
acceleration, to eliminate oscillation or bouncing and increase stability.
Drive Height
Lowering the drive will increase the propeller's ability to bite at take off
but excessive lowering can cause the back of the boat to feel loose and
decrease top end stability. Raising the drive helps eliminate oscillation
or bouncing and assist with top end stability, but excessively raising
the drive can reduce top speeds and cause cavitation.
If the conditions are questionable, adjust the prop strut down a bit to
reduce the likelihood of having the boat overturn. The motor mount
is slotted to allow you to move the motor slightly when adjusting the
propeller strut. Loosen the motor mounting screws when adjusting the
propeller strut angle trim and retighten after adjustment is complete. Use
a 3mm hex wrench and 7mm nut driver to loosen the bolt that attaches
the output to the bracket to adjust the height. Raise or lower the prop
strut. Tighten the bolt when adjustment is complete.
You may also turn the dual rate dial down to reduce rudder travel
in rough water conditions.
