    Default Nozzle = Out of The Water

    That jacks with your brain huh? Look at the boat and the nozzle is 80% out of the water when it goes by.

    Goes to show the work moving the boat is inside the pump. Or were only going 20% as fast as we could be lol

    Time to review the theory of jet propulsioin. Equal and oposite reaction.

    You want the water discharge to be in the air so the discharge water exits the pump at the maixmum velocity to obatin the maximum thrust.

    If the pump discharge exited in the water, the discharge would lose velocity and provide less thrust.

    I think......

    Default In thrust we trust

    No matter where the discharge is, the boat speed is dependent on thrust. The thrust is the same whether the discharge is under water, in the air or where ever. Thrust is the result of squirting all that water in the same direction. The water doesn't need to "push" against anything to generate thrust. The fact that the water is accelerated in the pump is what develops thrust. After the water leaves the nozzle, it doesn't matter what is hits, the work was already done in the pump.

    Friend just sent a pic. Yep I knew that was the case but it just screws with the brain. It's all the way out of the water and looks like the boat is on the ride plate.

    Once we get this thing to load some water it should pick up quite a bit.

    hence the term JET Like you say it does seem a little freaky the first time you see it. On my first jet boat
    I had someone drive so I could look to make sure
    I didn't have any leaks on the diverter. I crawled back
    over the engine cover and was like WTF??

    More like a push up bra only with quantifiable results. Once you unhook a push up bra and let them little buggers loose, what you see is what you get. hahaha
