Generl Informtion NOTE: Due to running hnges, some illustrtions my not e extly the sme s your drive unit. Servie proedures remin the sme unless otherwise noted. Priniples of Opertion The jet pump opertes y drwing wter into housing forwrd of the impeller. The wter is pressurized within the speilly designed housing nd then direted to the rer to provide thrust nd motion. - Reverse Gte (Shown In the Forwrd Position) d - Forwrd Motion - Wter Thrust - Nozzle (Rudder) d - Reverse Gte (Shown In the Forwrd Position) The jet pump is equipped with steerle nozzle (rudder) t the ft end of the pump housing tht direts the thrust of wter. The jet of wter n e direted right or left when the opertor turns the steering wheel in the respetive diretion. When the opertor turns the steering wheel to the right, for exmple, the nozzle turns to the right nd the jet fore from the nozzle pushes the stern of the ot to the left using the ow of the ot to turn right. Forwrd nd reverse drive nd the neutrl position re hieved y the position of reverse gte loted just ft of the nozzle. Forwrd drive hs the reverse gte lering the nozzle to llow ll the thrust to e direted stright k. Reverse drive hs the reverse gte overing the entire opening enough to divert the thrust forwrd. Neutrl position hs the reverse gte overing 75 perent of the nozzle to diret the wter strem forwrd nd downwrd,s well s kwrd. The shift position is ontrolled t the ontrol ox in the ot. - Reverse Gte (Shown In the Reverse Position) 90-831996R1 JUNE 1996 JET PUMP 5-1
