    flipping and jumping a super charged ski

    i really apologize if this is one of those "repeat" threads or if its one of those common sense threads but...

    1. is it true if you happen to become airborn and you are pressing the throttle.. you could blow the supercharger up ?

    2. i heard flipping a supercharged ski.. and it landing upside down could again, potentially blow the motor and/or the super charger..

    again im sorry if these questions are REALLY out there and stupid but.. im so used to running two strokes that im trying to understand the ins and outs of these machines so i can hopefully spend my summer on the water... and not in a shop lol

    No, you won't blow up your ski from flipping it over or jumping waves. BUT! if you keep the throttle pinned to the bar while the pump is out of the water you do increase the potential for engine damage of some form. From dropped valves to thrown rods. Premature wear of the SC clutches is also likely. There is a right way and a wrong way to abuse your ski and the wrong way will simply wreck it sooner.

    short answer DONT. These arent the light weight 2 stroke machines of years past. Jumping and hard landing can push the motor mounts thru the hull.

    i really should have elaborated so you guys dont get the wrong impression of me haha ... i dont plan on heading out the night before the next big hurricane and grabbing some 10 footers... i just want to make sure if i happen to catch a small wake from a boat and pop out of the water for a second i was going to be okay or if i had to slow down to a wake to avoid damage haha... i live near a pretty busy state channel so big boats are constintally zooming past and catching a wake is something i cant really avoid... i think i may be over thinking this and im listening to over inflated horror stories from 2 stroke guys haha

    Like I said, if you keep the throttle pinned when you do catch some air off a wake or decently sized wave, you will run the risk of having the engine over rev. And thats where a lot of damage can occur. Yes the engines have rev limiters, but they can't help much if the pump is not loaded with water. Imagine how easy it is to rev an engine on the trailor. You just have to be mechanically sympathetic, and come off the throttle just as you crest the wave so the engine does not rev free. Some people find it very hard to do!

    ....Anytime the ski becomes "UNHOOKED" from the water you really should learn to "float" the throttle at high RPM's due to the supercharger boost pressure rather than just releasing it all together
