Which operation on a pwc requires more than idle speed?

PWC means personal water craft, it can be any jet ski, water scooter or boater cycle. At idle speeds with a smaller amount of water pumping through the jet unit, the jet boat will lose some steering control and the maneuverability and will quickly slow down making it difficult to safely maneuver. As the hull detachable it’s planning state and hull resistance is increased. However, loss of steering control at low speeds can be astounded by lowering the reverse deflector slightly and increasing control - so an operator may escalate thrust and thus control without increasing boat speed itself.
