The recommended maintenance schedule includes an oil change every 50 hours or annually, checking the spark plugs every 100 hours, inspecting the impeller and jet pump every 100 hours, and ensuring the cooling system is flushed after each saltwater use.
If the Waverunner won't start, check the battery connections for corrosion, ensure the battery is fully charged, examine the fuses, and inspect the ignition system. Also, confirm that the lanyard is properly attached.
Yamaha recommends using Yamalube 4W 10W-40 for the FX Cruiser SHO, as it is specifically designed for their marine engines, providing optimal performance and protection.
To prevent corrosion, rinse the Waverunner with fresh water after each use, especially after saltwater exposure. Apply a protective anti-corrosion spray to metal parts and ensure the unit is stored in a dry environment.
If overheating occurs, check the cooling water intake for blockages, inspect the impeller and pump for damage, and ensure the water pump is functioning correctly. It's also crucial to check coolant levels if applicable.
To winterize, stabilize the fuel, change the oil and filter, flush the cooling system with antifreeze, clean and dry the Waverunner thoroughly, and store it in a cool, dry place away from direct sunlight.
Attach a garden hose to the flushing port, start the engine, turn on the water, let it run for a few minutes, turn off the water, and then shut down the engine. Always follow the manufacturer's instructions.
Improve fuel efficiency by ensuring the engine is well-maintained, keeping the hull clean and free of marine growth, using the recommended fuel type, and avoiding excessive idling.
Before use, check the fuel and oil levels, ensure all safety equipment is on board, test the throttle and steering controls, inspect the hull for damage, and confirm that the lanyard is functional.
To change the spark plugs, remove the engine cover, disconnect the spark plug wires, use a spark plug socket to remove the old plugs, install the new plugs by hand first, then tighten with a wrench, and reconnect the spark plug wires.
