Water Jet Hose

need to see if work on the jet ski / runs .. I know there's a way to do it at home with a water hose, but do not know how .. can someone tell me how?

Yes, you can usually connect a hose to the height of the test engine. Depending on the brand / model / year, you'll need an adapter kit to hook the flush pipe to the height. You can start a jet ski off the water without a hose, but should not operate for more than 15 seconds (and then let it cool for 15 minutes before firing it again).

If I make / model / year of jet-ski you have, I might be able to guide you through how to connect.
