Besides, if remain starting position on lands, the Engine RPM will stay at high rate due to no power loading , water resistance.

If the engine is run at full speed without a power load, it may cause the engine to "overspeed" Phenomenon- the engine continues to run uncontrolled even the safety key is removed.(if this happen, immediately block the carburetor intake tunnel to choke the engine stop).

So if you want to test full power of the surfboard, please do it on water.
