THE HOSE (FLUSH KIT) IS FOR FLUSHING SALT WATER AND DEBRIS OUT OF THE EXHAUST SYSTEM ONLY!!!
This means it is NOT for testing and tuning on the trailer
It is NOT REQUIRED (on any ski) for the water to be on to start the motor.
If you want to test start a ski and let it run for 30 seconds or a minute, that is fine. You won’t hurt anything by running it “dry” for these lengths of time.
