Kawasaki Jet Ski 550–1100 Service & Repair Manual, 1992–1998

Aftermarket service and repair manual for Kawasaki Jet Ski 550, 650, 750, 900, and 1100 series within the 1992–1998 production window. It covers two- and three-cylinder engines, with separate procedures and specifications for standard and high-performance configurations.

PDF Bookmarks and Wiring Detail

Search, navigation, and diagram detail: PDF text search is not available. Embedded bookmarks link to the contents, all eleven chapters, the appendix, and the wiring diagrams. Small labels on the denser wiring diagrams require zooming; some closely packed wire codes remain difficult to distinguish.

One printable 296-page PDF: five contents pages, 280 chapter pages, and an 11-page appendix containing six wiring-diagram pages. The contents and appendix are included in the total.

Two-Stroke Engine, Fuel, and Jet-Pump Service

These selected service topics form part of a wider manual that also discusses replacement-part selection and throttle-opening-limiter operation.

• Engine repair: Step-by-step removal, internal disassembly, inspection, reassembly, installation, and engine-to-pump alignment procedures for two- and three-cylinder engines.

• Keihin fuel and oil systems: CDK-34, CDK-38, and CDK-40 carburetor overhaul, remote and integral fuel-pump service, oil-injection delivery testing, and air purging.

• Ignition and charging: CDI diagnosis, exciter, pulser, pickup, and ignition-coil tests, dynamic magneto timing checks, and charging-output and resistance measurements.

• Electrical service: Starter-relay testing, starter-motor overhaul, switch checks, electric bilge-pump and fan tests, temperature warnings, and electric-trim service.

• Jet pumps and controls: Mixed-flow and axial-flow pump repair, impeller-clearance inspection, 550 shimming, bearing-housing service, and steering, reverse, and trim cable adjustments.

• Troubleshooting references: Six engine and jet-pump decision charts, wiring and color-code diagrams, exploded views, torque tables, tune-up data, and component inspection limits.

With full engine and pump teardown procedures, meter-based ignition testing, pressure and vacuum checks, and model-specific pullers and holders, this repair manual is suited to experienced owners and working technicians. Its routine flushing, lubrication, storage, and pre-season sections are more accessible, but major repair work assumes workshop skill and equipment.

Exact Model Coverage

The manual's overall statement runs through 1998; “and on” is the wording used for later models in its own coverage and specification tables. The procedures address stock engines and jet drives; aftermarket performance modifications are outside the book's scope.

Carburetion, Lubrication, and Seasonal Maintenance

The carburetor chapter distinguishes the single CDK-38 installation on the 550, the remotely supplied CDK-34 on the 650, single CDK-40 standard 750 setups, twin CDK-40 high-performance setups, and triple CDK-38 installations on the 900/1100. The center carburetor in a triple installation has no integral fuel pump.

Service instructions cover cleaning, inspection, assembly, priming, bench and running adjustments, high-altitude setup, remote-pump pressure and volume checks, and oil-injection delivery testing and air purging.

Maintenance content covers cooling and bilge flushing, corrosion control, fuel and oil filtration, fiberglass hull care, winter storage, pre-season checks, and submerged-engine service for salt water, fresh water, or submersion while running.

Internal Engine Inspection and Pump Variants

Engine inspection extends to crankshaft runout, connecting-rod play, piston rings, cylinder wear and honing, and block or cylinder-head warpage. Reed-block service applies to reed-equipped engines; the 550 uses a different intake design.

The 550 mixed-flow pump has its own impeller-shimming procedures. Other covered series use axial-flow pumps without that shimming arrangement. Bearing-housing teardown covers the older serviceable design; newer maintenance-free housings are addressed through removal and replacement.

Electrical Diagnosis, Drawings, and Special Tools

The troubleshooting charts address an engine that will not start, starts and shuts down, misfires, lacks power, makes abnormal noise, or has a jet-pump fault. They connect symptoms with system checks, helping distinguish fuel, ignition, compression, and pump problems before selecting the detailed service procedure.

Ignition timing adjustment applies to the 550 and 650 series; timing on the other covered engines is non-adjustable. CDI troubleshooting uses commonly available instruments, with the manual explaining the limits of resistance testing compared with a Kawasaki ignition tester.

Visual references include series-specific wiring diagrams, electrical-box starter and relay schematics, Keihin carburetor and remote-pump exploded drawings, engine exploded views, and axial- versus mixed-flow pump sections.

Engine tools include piston-pin puller 57001-910, flywheel holder 57001-1313, and coupler holder 57001-1230. Pump tools include impeller wrench 57001-1228, impeller holder 57001-1393, and oil-seal/bearing remover 57001-1058.

Repair Cautions and Service Limits

The manual warns that filing the molded protrusion from the bilge-hose fitting can reverse the siphon effect and pump water into the hull. On the 550 mixed-flow pump, installing the impeller shaft without the seal protector can split the seal lips, let pressurized water reach the bearings, and seize the pump.

Electric-trim coverage is limited to illustrated removal, opening, reassembly, and installation rather than a full internal overhaul. Fuel-system and spark-producing tests require a ventilated, vapor-free bilge, proper battery isolation, and the test setup specified in the manual.

Fuel-Pressure and Reed-Clearance Examples

The 650-series remote fuel-pump pressure test specifies at least 2 psi with the engine warmed up and operating at full throttle.

For reed-block inspection on the 650, 750, 900, and 1100 series, maximum reed-petal clearance is 0.008 in (0.2 mm).
