Engine off. reverse cup up

i heard there was a way to shut off the engine of a seadoo spark trixx with the reverse cup up. The way it is when i regularly shut down the engine the cup fits down as if it’s in reverse. then its as low or lower than the bottom of the hull. dragging it down the beach i noticed it cups Sand the whole way.
anyways i heard you pull the emergency stop while throttle is on and continue to hold throttle on till engine stops. ( or something like that).
tried a few things- nothing works.
anyone heard of this is know how to do it?

If you have VTS installed:

Starting with everything off, insert the key and press the start button momentarily (turns on electronics, does not turn over engine). Press the mode button and hold the IBR lever and use the trim button to move the bucket.
