I found if you have at least a foot of clean water under the hull you could idle to deeper water before touching the throttle without drawing any debris in.

I have beached jet skis many times but always get it heading for shore and try to shut it off in about 2 feet of water and let the headway take care of the rest.

When I sucked up weeds in a Yamaha jet boat you could tell right away by the reduced power and minor shaking, out of balance feel. On some occasions I could get it back up to speed and then shut the motor off. Many times the suction of the passing water (without any suction from the motor) would clear the intake screens of debris. Sometimes the only way to clear the intake was to get under it and do it by hand. In time, you make fewer errors and learn to avoid these problems.
I forgot to thank you for this--I wouldn't have known the pump is constantly running, even in neutral.

So, whenever I'm in a situation where something is close enough to be sucked in, I should make sure the machine is off. Check!
