Refer to manual for exact specifications
Horsepower:
Typically around 110-120 HP (verify with manual)
Torque:
Refer to manual for exact specifications
Fuel Delivery:
Carburetor(s) - likely Mikuni VM series or similar twin/triple carb setup.
Fuel Type:
Unleaded gasoline (refer to manual for octane rating and oil mixture ratio for 2-stroke pre-mix if applicable).
Lubrication System:
2-stroke oil injection system (automatic oil injection) or pre-mix (verify with manual).
Cooling System:
Closed-loop cooling system with an impeller, water pump, and heat exchanger.
Type:
Direct drive, centrifugal clutch, coupled to an axial flow jet pump.
Optional Transmission:
N/A (standard configuration for personal watercraft)
Features:
Single forward gear, reverse (if equipped, typically via a diverter mechanism), ignition-based engine cut-off for stopping.
Transmission Fluid Spec:
Lubrication is typically through 2-stroke engine oil mixed with fuel or via an injection system. No separate transmission fluid in the automotive sense.
Engine Oil Change:
Refer to manual for specific intervals (typically based on hours of operation or annually). For 2-stroke, oil mixture is critical.
Spark Plug Inspection:
Refer to manual (e.g., every 50-100 operating hours or annually).
Fuel Filter Replacement:
Refer to manual (e.g., annually or based on operating hours).
Impeller Inspection:
Regular inspection for debris and wear, particularly after operating in shallow or debris-filled water.
Engine Oil Type:
Specific 2-stroke marine oil (e.g., API-TC, JASO FD rated) - Refer to manual for precise grade and brand recommendations.
Coolant Type:
If a closed-loop system, typically a specific marine coolant or a suitable antifreeze/water mixture. Refer to manual for type and capacity.
Common Issues:
Carbon buildup in exhaust ports, carburetor synchronization problems, wear on jet pump seals, potential ignition system issues, hull stress cracks (especially from improper storage or trailering).
Maintenance Focus:
Due to its 2-stroke nature, proper fuel/oil mixture, regular decarbonization of the engine, and flushing the cooling system are critical.
Kawasaki Marine History:
Kawasaki has a long history of innovation in marine propulsion, known for performance-oriented personal watercraft.
Jh900 Positioning:
The JH900 series was a significant model in Kawasaki's Jet Ski lineup during the late 1990s, offering a powerful 3-cylinder engine in a versatile platform.
Production Period:
1990s, with the JH900 model specifically produced around 1998-2003, evolving into models like the STX series.
