The final step is to check for leaks. Attach your hose to the other end of the quick connect, and simply press the two quick connect pieces together. Its that simple!
First, start your ski. Second, quickly turn on the water. Now run your ski at partial throttle for a couple of minutes. This is the part I hate, since my ski is so LOUD! Shut off the water, rev the engine to clear the exhaust of water, then stop it. Thats it, your done!
Do this on a regular basis, and its like adding extra hours to the life of your engine! Happy flushing.
