PP Jet Propulsion Units

Kort Propulsion Co., Ltd., world famous for the Kort Nozzle Rud- ders, also markets other popular marine equipment such as PP Jet high-speed pump systems from 200 to 4,000 hp.

These are integrated packages for propulsion and maneuvering.

The units consist of a pump, a steer- ing nozzle and a reverse bucket.

The pump is of a mixed flow type which draws water from underneath -the boat, through an impeller and stator then ejects through a steer- ing nozzle.

PP Jet uses glass reinforced plas- tic as a major static component for its water jets. The range of jet units are now being built with a mixture of glass fiber, kevlar and carbon fiber. Therefore these units are reported to be corrosion resistant and lightweight. Bronze or stain- less steel are used for parts which are in contact with sea water.

PP Jet offers a wide range of units which can be used aboard a variety of different vessels, ranging from small sports boats to fast fer- ries. The units can also be made for gasoline or diesel applications.

The P.P. model 65 jet unit is de- signed specifically for sports boats and small workboats with engines from 60 to 200 horsepower. The boat must weigh a maximum of one ton in order for the unit to operate properly. The weight of the unit is 55 pounds.

The P.P. model 90 and model 90G are intended for commercial or lei- sure vessels with weights of up to two tons. The P.P. 90 weighs about 132 pounds and the 90G weighs 154 pounds.

The P.P. 115,140 and 170 models are all designed for commercial uses and for different size vessels, rang- ing from about 2 tons up to 10 tons.

The model 210, 250 and 300 jet units are also available for larger applications.

The engines range from 20 to 4,000 hp for diesel engines with maximum rpm from 6,000 to 1,400.

Some of the features which the water jets provide are oil or water lubricated rear bearing, face seals on larger jets, built-in ducting with shapes to match that of the hull, low water-born noise capacity, adjust- able propellers/duct tip clearance and simple design for ease of main- tenance.
