Vehicle Starting and Running

Breaking in the Engine

CAUTION:  

Make sure you understand all engine instructions before attempting to start the engine.  

Failure to follow all instructions can lead to damage to your vehicle, property damage and bodily injury.

CAUTION:

  Always keep all body parts, hair and dangling or loose items away from a spinning propeller, as these 

could become entangled.

1.

  Remove the canopy. 

2

.  Power on your transmitter, then power on the 

receiver. 

3.

  Press the priming bulb several times until it becomes 

filled with fuel. This is not necessary if the engine has 

been run recently.

4.

  With the boat on a stand and the propeller unobstructed, 

pull the starter cord in a quick continuous motion to start 

the engine. The engine should start within 6 pulls.  

5. 

Replace the canopy before placing the boat in the 

water.

Break in the engine by running slowly for the first half 

tank of fuel (about 25 minutes).

NOTICE:  

Do not adjust carburetor settings during 

break-in. Doing so will cause engine damage.

When the boat is moving forward, ensure water flows 

out of the coolant outlets. If water is not flowing out of 

the coolant outlets, remove any blockage from the rudder 

inlet and coolant system or the engine and tuned muffler 

may overheat.
