Jet Boat Service & Repair

What is a Jet Boat?
A jet boat is propelled by a jet of water ejected from the rear of the boat. Unlike a motorboat that uses an external propeller in the water below or behind the boat, a jet boat, pulls water from under the boat through an intake into a pump-jet inboard, before expelling it through a nozzle located outside of the transom. Jet boats often include a flat, vertically hinged piece of aluminum that helps with steering. Common performance modifications include a nozzle diverter attachment.
