of a PWC
watercraft, or PWC, are small jet-drive propelled powerboats.
The pumps draw water into the housing, with an impeller, which
pressurizes the water and forces it through the steerable nozzle,
pushing the boat forward. (See jet pump diagram
exist in three main styles: stand-up, sit-down sport class (one
or two people), and sit-down three or four-person. The stand-up
style carries only one person who stands while operating the vessel,
while the sit-down styles have seats for one to four people.
main components of a PWC are the:
- the body of the boat.
- flat surfaces such as the seat, foot wells, and compartment
- mounted on the handle bars, regulates the amount of fuel delivered
to the engine and controls the speed.
nozzle - located at the rear of the vessel and controlled
by the handlebars.
in-take - located on the underside of the hull, this is where
the impeller pulls water into the vessel.
controls include the start and stop switches and the cutoff or
"kill" switch with attached lanyard.
the steering handlebars of the PWC are turned to the right, the
steering nozzle also turns to the right. The stream of water pushes
the back of the boat to the left, causing the PWC to turn right.
It is important to note that the PWC loses steering ability if
it loses power or the stream of water for any reason.
PWC are equipped with a cut-off switch that must be attached to
the operator by a lanyard. If the rider falls off, the lanyard
is pulled and the cutoff switch engages to shut down the engine.
The PWC engine will stop, and the watercraft will glide to a stop
PWC have an automatic idle and self-circling device. If the rider
falls off, the PWC will circle slowly in the area until the rider
can safely reboard.
