What to do if my ProBoat Impulse 31 PRB4250B will not connect after binding?
- C
  Connie SmithAug 22, 2025
  If your ProBoat Toy does not connect after binding, here are a few things to check: The transmitter might be too close to the boat during the connecting process, so move the powered transmitter a few feet away, disconnect, and reconnect the battery. The boat or transmitter could be near metal objects or other wireless sources, so move to a different location. Ensure the bind plug is removed after binding by rebinding the transmitter and removing the plug before cycling power. Also, check battery levels and replace or recharge if low. The transmitter may have been bound to a different model, so rebind the boat to the transmitter. Finally, ensure the ESC switch is powered on.

  Stephanie ValentineAug 26, 2025
  If your ProBoat Toy is not responding to the throttle, there are a couple of things you can check. First, ensure that the throttle servo travel is set to 100% or greater. Second, verify that the throttle channel is not reversed; if it is, reverse the throttle channel on the transmitter.

Why does the rudder on my ProBoat Impulse 31 PRB4250B not move?
- M
  Mr. Kenneth Greene MDAug 27, 2025
  If the rudder on your ProBoat Toy is not moving, it could be due to several reasons: There may be damage to the rudder, linkage, or servo, so replace or repair any damaged parts and adjust the controls. A wire may be damaged or connections may be loose, so check the wires and connections and connect or replace them as needed. The transmitter may not be bound correctly, or the incorrect model was selected, so re-bind or select the correct model in the transmitter. The BEC (Battery Elimination Circuit) of the ESC may be damaged, so replace the ESC. Finally, make sure the ESC switch is on.

Why is my ProBoat Impulse 31 PRB4250B making extra noise or vibrating?
- A

  Extra noise or vibration in your ProBoat Toy could be due to a damaged propeller, shaft, or motor. Replace any damaged parts. Alternatively, the propeller might be out of balance, so balance or replace the propeller.

What to do if ProBoat Impulse 31 PRB4250B Toy dives in the water or takes on water?
- R
  ryandanaSep 1, 2025
  If your ProBoat Toy tends to dive or take on water, it might be because the boat hull is not completely closed. Dry out the boat and ensure the hatch is fully closed on the hull before returning the boat to the water. Another reason might be that the center of gravity is too far forward, so move the batteries back in the hull. Also, check the trim tabs on the back of the boat; if they are angled incorrectly, adjust them. Angle each trim tab up a small amount to lift the bow or down a small amount to lower the bow.

Why does my ProBoat Impulse 31 PRB4250B Toy tend to turn in one direction?
- M
  Margaret ChavezSep 4, 2025
  If your ProBoat Toy tends to turn in one direction, the rudder or rudder trim may not be centered. Repair the rudder or adjust the rudder and rudder trim for straight running when the control is at neutral. Alternatively, the vertical fins may be angled incorrectly, so angle the fins a small amount right or left so that the boat goes straight when the rudder is at neutral.

Why does the motor power pulse and then lose power on my ProBoat Impulse 31 PRB4250B?
- J
  Joseph MooreSep 7, 2025
  The motor power pulsing and then losing power on your ProBoat Toy could be due to several reasons. The ESC might be using the default soft Low Voltage Cut-off (LVC), so recharge the boat battery or replace the battery if it is no longer performing well. Weather conditions might be too cold, so postpone use until the weather is warmer. The battery could be old, worn out, or damaged, so replace it. Finally, the battery C rating might be too small, so use the recommended battery.

How to correct reversed controls on my ProBoat Impulse 31 PRB4250B?
- W
  William BirdSep 10, 2025
  If the controls on your ProBoat Toy are reversed, it means the transmitter settings are reversed. To correct this, perform the Control Direction Test and adjust the controls on the transmitter appropriately.

What to do if my ProBoat Toy will not bind?
- J
  Jonathan GilbertSep 12, 2025
  If your ProBoat Toy will not bind, it could be due to several reasons. The transmitter might be too near the boat during the binding process, so move the powered transmitter a few feet from the boat, then disconnect and reconnect the battery to the boat. The boat or transmitter might be too near a large metal object, wireless source, or another transmitter; in this case, move the boat and transmitter to another location and attempt binding again. Check if the bind plug is not installed correctly and install it to bind the boat to the transmitter. Also, the boat or transmitter battery charge may be too low, so replace or recharge the batteries. Finally, make sure the ESC switch is on.

Why is the motor or ESC overheating on my ProBoat Impulse 31 PRB4250B?
- C
  Calvin FullerSep 12, 2025
  If the motor or ESC is overheating on your ProBoat Toy, it could be due to blocked water cooler tubes. Clean or replace the water tubes.
