To facilitate actual operations, notes, illustrations, photographs, cautions, and detailed descriptions have been included in each chapter wherever necessary. This section explains the items that require particular attention during the removal and reinstallation or disassembly and reassembly of general parts. Especially note the following:
Kawasaki Diagnostic System (KDS) Software KDS software that runs on Windows personal computer (PC) will be available as a diagnostic tool for watercraft with Kawasaki DFI system. You need the following items to use the KDS. Item KDS Software Version 3.â–Ą (CD-ROM, Updated Version) KDS3 Adapter
Communication Cables KDS Adapter Cable
P/No. 57001-1650 57001-1648 and 57001-1724 or 57001-1725 57001-1649 and 57001-1688 or 57001–1745 57001-1696
The connectors for the communication cable and KDS adapter cable are located in the front. Connect the communication cable to the KDS connector (4-pin) [A] and the KDS adapter cable between the ignition switch (immobilizer amplifier) lead connectors (6-pin) [B].
Adjustments Adjustments shall be made in accordance with the Periodic Maintenance Chart or whenever troubleshooting or presence of symptoms indicate that adjustments may be required. Whenever running of the engine is required during maintenance it is best to have the watercraft in water.
CAUTION Do not run the engine without cooling water supply for more than 15 seconds, especially in high revolutionary speed or severe engine and exhaust system damage will occur.
Auxiliary Cooling An auxiliary cooling supply may be used if the watercraft cannot be operated in water during adjustments. If possible, always operate the watercraft in water rather than use an auxiliary cooling supply.
GENERAL INFORMATION 1-3 Before Servicing a standard garden hose [A] and a garden hose • Obtain adapter [B] as shown. C: Garden Hose Fitting of Adapter D: Flushing Fitting of Adapter E: Thread: Rp 3/4
○Optional part (P/No. 92005-3746) is available as a garden hose adapter.

a garden hose adapter [A] onto the flushing fitting • Screw [B]. a garden hose [C] to a garden hose adapter and • Attach secure the hose clamp [D].
the garden hose to a faucet. Do not turn on the water until the engine is running and turn it • Attach off immediately when the engine stops. The engine requires 2.4 L/min (2.5 qts/min) at 1 800 rpm and 7.0 L/min (7.4 qts/min) at 6 000 rpm.
CAUTION Insufficient cooling supply will cause the engine and/or exhaust system to overheat and severe damage will occur. Excessive cooling supply may kill the engine and flood the cylinders, causing hydraulic lock. Hydraulic lock will cause severe damage to the engine. If the engine dies while using an auxiliary cooling supply, the water must be shut off immediately.
CAUTION Always turn the boat on its left side. Rolling to the right side can cause water in the exhaust system to run into the engine, with possible engine damage.
1-4 GENERAL INFORMATION Before Servicing CAUTION Turn the capsized boat clockwise so that the port side always faces downward. Turning counterclockwise can cause water in the exhaust system to run into the engine, with possible engine damage.
Battery Ground Before completing any service on the watercraft, disconnect the battery wires from the battery to prevent the engine from accidentally turning over. Disconnect the ground wire (–) first and then the positive (+). When completed with the service, first connect the positive (+) wire to the positive (+) terminal of the battery then the negative (–) wire to the negative terminal.
Edges of Parts Lift large or heavy parts wearing gloves to prevent injury from possible sharp edges on the parts.
Solvent Use a high flush point solvent when cleaning parts. High flush point solvent should be used according to directions of the solvent manufacturer.
GENERAL INFORMATION 1-5 Before Servicing Cleaning Watercraft before Disassembly Clean the watercraft thoroughly before disassembly. Dirt or other foreign materials entering into sealed areas during watercraft disassembly can cause excessive wear and decrease performance of the watercraft.
Arrangement and Cleaning of Removed Parts Disassembled parts are easy to confuse. Arrange the parts according to the order the parts were disassembled and clean the parts in order prior to assembly.
Storage of Removed Parts After all the parts including subassembly parts have been cleaned, store the parts in a clean area. Put a clean cloth or plastic sheet over the parts to protect from any foreign materials that may collect before re-assembly.
Inspection Reuse of worn or damaged parts may lead to serious accident. Visually inspect removed parts for corrosion, discoloration, or other damage. Refer to the appropriate sections of this manual for service limits on individual parts. Replace the parts if any damage has been found or if the part is beyond its service limit.
Replacement Parts Replacement Parts must be KAWASAKI genuine or recommended by KAWASAKI. Gaskets, O-rings, Oil seals, Grease seals, circlips or cotter pins must be replaced with new ones whenever disassembled.
1-6 GENERAL INFORMATION Before Servicing Assembly Order In most cases assembly order is the reverse of disassembly, however, if assembly order is provided in this Service Manual, follow the procedures given.
Tightening Sequence Generally, when installing a part with several bolts, nuts, or screws, start them all in their holes and tighten them to a snug fit. Then tighten them according to the specified sequence to prevent case warpage or deformation which can lead to malfunction. Conversely when loosening the bolts, nuts, or screws, first loosen all of them by about a quarter turn and then remove them. If the specified tightening sequence is not indicated, tighten the fasteners alternating diagonally.
Tightening Torque Incorrect torque applied to a bolt, nut, or screw may lead to serious damage. Tighten fasteners to the specified torque using a good quality torque wrench.
Force Use common sense during disassembly and assembly, excessive force can cause expensive or hard to repair damage. When necessary, remove screws that have a non -permanent locking agent applied using an impact driver. Use a plastic-faced mallet whenever tapping is necessary.
Gasket, O-ring Hardening, shrinkage, or damage of both gaskets and O-rings after disassembly can reduce sealing performance. Remove old gaskets and clean the sealing surfaces thoroughly so that no gasket material or other material remains. Install new gaskets and replace used O-rings when re-assembling
GENERAL INFORMATION 1-7 Before Servicing Liquid Gasket, Locking Agent For applications that require Liquid Gasket or a Locking agent, clean the surfaces so that no oil residue remains before applying liquid gasket or locking agent. Do not apply them excessively. Excessive application can clog oil passages and cause serious damage.
Press For items such as bearings or oil seals that must be pressed into place, apply small amount of oil to the contact area. Be sure to maintain proper alignment and use smooth movements when installing.
Ball Bearing Do not remove pressed ball or needle unless removal is absolutely necessary. Replace with new ones whenever removed. Press bearings with the manufacturer and size marks facing out. Press the bearing into place by putting pressure on the correct bearing race as shown. Pressing the incorrect race can cause pressure between the inner and outer race and result in bearing damage.
Oil Seal, Grease Seal Do not remove pressed oil or grease seals unless removal is necessary. Replace with new ones whenever removed. Press new oil seals with manufacture and size marks facing out. Make sure the seal is aligned properly when installing.
Apply specified grease to the lip of seal before installing the seal.
1-8 GENERAL INFORMATION Before Servicing Circlips, Cotter Pins Replace circlips or cotter pins that were removed with new ones. Take care not to open the clip excessively when installing to prevent deformation.
Lubrication It is important to lubricate rotating or sliding parts during assembly to minimize wear during initial operation. Lubrication points are called out throughout this manual, apply the specific oil or grease as specified.
Direction of Engine Rotation When rotating the crankshaft, by hand, the free play amount of rotating direction will affect the adjustment. Rotate the crankshaft to positive direction (counter-clockwise viewed from stern sinde).
Electrical Wires A two-color wire is identified first by the primary color and then the stripe color. Unless instructed otherwise, electrical wires must be connected to those of the same color.
Instrument Use a meter that has enough accuracy for an accurate measurement. Read the manufacture’s instructions thoroughly before using the meter. Incorrect values may lead to improper adjustments.
GENERAL INFORMATION 1-9 Before Servicing Harness Connector Apply grease [A] on all connectors of harness [B] for water resistance. Do not apply grease on the only connector of inlet air pressure sensor.
