PWCs are propelled by drawing water into a pump and then forcing it out under pressure through a steering nozzle at the back of the unit. This "jet" of pressurized water is directed by the steering control—when the steering control is turned, the steering nozzle turns in the same direction. For example, if the steering control is turned right, the nozzle turns right and the jet of water pushes the back of the vessel to the left, which causes the PWC to turn right.
Most PWCs do not have brakes. Always allow plenty of room for stopping. Just because you release the throttle or shut off the engine does not mean you will stop immediately. Even PWCs that have a braking system do not stop immediately.
Remember—no power means no steering control …
Most PWCs and other jet-drive vessels must have power in order to maintain control. If you allow the engine on these PWCs to return to idle or shut off during operation, you lose all steering control. The PWC will continue in the direction it was headed before the engine was shut off, no matter which way the steering control is turned. New PWCs allow for off-throttle steering.
