    Cavitation

    Hi Guys...

    What happens to the pump/impeller on a ski when you go over heavy whitewater, like a breaking wave? it can't be good for the ski, what type of damage is caused by it?

    Air mixed into the white water would be a form of jet pump ventilation (air bubbles), not cavitation (vacuum bubbles).

    For the few seconds you are riding in the white water, the impeller will be compressing the air bubbles, so thrust is reduced. As long as you don't go heavy on the throttle, the engine shouldn't excess-rev.

    The cooling system (if open loop) will get air bubbles pumped through it, but it will quickly purge the air out as soon as the jet pump gets hold of solid water again.
