The recommended fuel type for the Yamaha SuperJet 700 2004 is regular unleaded gasoline with a minimum octane rating of 87.
It is recommended to perform maintenance every 50 hours of operation or at least once a year to ensure optimal performance.
Use a high-quality 2-stroke marine engine oil to ensure proper lubrication and performance.
Start by checking the battery charge, inspecting the spark plugs, and ensuring the fuel system is functioning correctly.
The correct spark plug gap should be set to 0.028 to 0.031 inches (0.7 to 0.8 mm).
To winterize, drain the fuel, fog the engine with a fogging oil, lubricate moving parts, and store it in a dry place.
Overheating could be caused by a blockage in the cooling system, a faulty thermostat, or low coolant levels. Ensure the cooling intake is clear and inspect the cooling system.
To adjust the carburetor, locate the low and high-speed adjustment screws, and turn them as needed to achieve a smooth idle and optimal performance.
Check for debris around the impeller, inspect the drive shaft for damage, and ensure all engine mounts are secure to reduce vibration.
To improve performance, ensure regular maintenance, consider upgrading the impeller, and keep the hull clean and free of damage.
