Moving the batteries to the front or back can significantly

affect the boat's performance.

1. Move the batteries toward the rear of the boat

to raise the front of the hull out of the water for

increased speed.

2. Move the batteries toward the front of the boat for

faster initial acceleration, to eliminate oscillation or

bouncing, and to increase stability.

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 (A) 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.

1. Power off the ESC.

2. Disconnect the batteries.

3. Power off the transmitter.

4. Remove the batteries from

the boat.

 Always store the boat open

(without the hatch and inner liner

sealed) or moisture may cause

mold and mildew to grow in

the boat.

• Prolong motor life by preventing

overheating conditions. Undue

motor wear results from frequent

turns, stops and starts, pushing

objects, boating in rough water

or vegetation and boating

continuously at high speed.

• Over-temperature protection is

installed on the ESC to prevent

circuit damage, but cannot

protect the motor from pushing

against heavy resistance.
