Yamaha XLT800 Waverunner 2002 Owner's Manual

Use Yamalube 2-W oil, which is specifically formulated for Yamaha 2-stroke engines, to ensure optimal performance and engine protection.
Check the battery for charge and connections, inspect the spark plugs for wear or fouling, and ensure the fuel system is delivering fuel properly.
Perform an oil change every 50 hours, replace spark plugs every 100 hours, and check the impeller and wear ring annually.
Attach a garden hose to the flush port, start the engine, and run water through the system for about 5 minutes to remove salt and debris.
Check for blockages in the cooling intake, ensure the flush hose connection is secure, and inspect the impeller for damage.
Use the correct oil mixture ratio, maintain a steady throttle, avoid rapid acceleration, and ensure the hull is clean and free of marine growth.
Drain the fuel or add a stabilizer, flush the cooling system, lubricate moving parts, and store the Waverunner in a dry, sheltered area.
Remove the engine cover, disconnect the spark plug wires, use a spark plug socket to remove the old plugs, and install new plugs with the correct gap.
Check the impeller and wear ring for damage or debris, and ensure the engine mounts are secure and not worn out.
Inspect the hull for cracks, check the drain plugs are secure, and ensure the bilge pump is operational.
