Pro Boat PRB4000BDC - Manual (Page 7)

7
Use a 3mm hex wrench and 7mm open end
wrench to loosen the two bolts that attach
the motor to the mount to adjust the trim.
Finding the proper trim angle will allow the
boat to turn correctly without sacrificing high-
end performance.
Outboard Height
Lowering the outboard will increase steering
response but excessive lowering can increase
resistance that can decrease top speeds.
Excessively raising the outboard can cause
hooking and lessen the ability to turn. This
can also cause cavitation.
Use a 3mm hex wrench to loosen the four
bolts that attach the motor mount to the hull
to adjust the height.
Center of Gravity
Moving the batteries to the front or back can
significantly affect the boat's performance.
Move the batteries toward the rear of the
boat to raise the front of the hull out of the
water for increased speed.
Move the batteries to the front of the boat
for faster initial acceleration, to eliminate
porpoising and increase stability.
