I am having a problem with a jazz sportjet. The boat will plane but cavate real bad if you push the throttle all the way down. It acts just like it is spinning out and does not have enough water to push out in order to propell it forward. if you pull back on the lever it will stop and push the water through enough to make the boat do about 20mph(just a estimate because speedo is broke). but as soon as you push lever back forward to make it go faster, it will act as if the impeller is spinning out. Can you point me into the right direction as I do not want to tear apart the pump to get at the impeller if that could not be the problem. as for the ride plate which I have seen on this forum that could cause a problem with this issue, it appears to be ok. Thank you for any help you can provide me.
