Normal sound. Its the engine over-revving because when out of the water you aren't taking water thru the jet pump.

Keep jumping waves and eventually you'll be rebuilding the engine too.

Let off the throttle when getting airborne. Once you learn to time the jumps it works pretty well. Even the racing go fast boats go airborne, that is why they have a driver and a throttle man. The throttle man pulls back when he sees its launching, then throttles back up as soon as the drive hits the water.

The sound is just a result of how the engine works. When there is nothing pushing on the impeller except air , the impeller speeds up and causes the engine to rev. Even going slow you sometimes get air, but going slower is the best way to avoid it. Other than that, nothing you can do.
