Yamaha GP1300R Waverunner 2007 Owner's Manual

The recommended maintenance schedule includes regular checks every 25 hours or annually, whichever comes first. Key tasks include inspecting and cleaning the spark plugs, checking the fuel system, lubricating moving parts, and inspecting the hull for damage.
If your Waverunner won't start, check the battery connections and ensure the battery is fully charged. Inspect the spark plugs and replace if necessary. Check the fuel level and ensure there are no obstructions in the fuel line.
Use Yamalube 2-W oil or a high-quality 2-stroke engine oil. The oil should be changed every 50 hours or annually, whichever comes first, to ensure optimal performance and engine longevity.
To store your Waverunner, clean it thoroughly, drain all water from the engine, add a fuel stabilizer, and remove the battery. Store the battery in a cool, dry place and keep the Waverunner covered to protect it from dust and moisture.
If overheating occurs, stop the engine immediately. Check for blockages in the cooling system, such as debris in the intake grate or cooling lines. Ensure the cooling hose connections are secure. Restart the engine only after resolving these issues.
Regularly inspect the impeller and jet pump for damage or debris. Remove any foreign objects and check for signs of wear. Replace the impeller if damaged to ensure optimal performance. Lubricate the bearings periodically.
Poor acceleration can be caused by a clogged fuel system, worn spark plugs, or a damaged impeller. Inspect and clean the fuel filter, replace spark plugs if necessary, and check the impeller for damage or debris.
To replace the spark plugs, first remove the seat and access the engine compartment. Disconnect the spark plug wires and use a spark plug socket to remove the old plugs. Install new plugs, ensuring they are properly gapped, and reattach the wires.
Use unleaded gasoline with a minimum octane rating of 87. Avoid using ethanol-blended fuels above E10 to prevent potential engine damage or performance issues.
To prevent corrosion, rinse the Waverunner with fresh water after each use, especially if used in saltwater. Apply a corrosion inhibitor to metal parts and ensure the hull is thoroughly dried before storage.
