Yamaha VX, VX Deluxe, VX Cruiser, VX Limited Waverunner 2017 Owner's Manual

Start by checking the engine oil level, inspecting the spark plugs, and ensuring that the battery is fully charged. Verify the impeller and cooling system for any debris or blockages. Additionally, check the hull and steering mechanisms for damage or wear.
It is recommended to use Yamalube 4W 10W-40 oil for the Yamaha VX Cruiser 2017, as it is specifically designed to provide optimal performance and protection for Yamaha's four-stroke engines.
First, check the battery connections to ensure they are secure and corrosion-free. Verify that the battery is charged. Inspect the fuse box for any blown fuses. If the problem persists, examine the spark plugs and replace them if necessary.
To winterize your VX Limited Waverunner, start by cleaning and drying it thoroughly. Add a fuel stabilizer to the tank and run the engine for a few minutes. Remove the battery and store it in a cool, dry place. Use a cover to protect the Waverunner from dust and moisture.
After saltwater use, flush the engine with fresh water to remove salt and debris. Rinse the exterior and undercarriage with fresh water. Apply a corrosion inhibitor to metal parts and inspect the hull and impeller for any damage or wear.
Begin by removing the engine cover to access the spark plugs. Use a spark plug socket to unscrew and remove the old plugs. Check the gap on the new plugs, then install them by hand before tightening with the socket. Reattach the engine cover once finished.
Check the cooling water intake for blockages or debris. Ensure the water pump is functioning correctly. Inspect the cooling system hoses for leaks or damage. If the issue continues, it may require professional servicing to diagnose internal engine problems.
Regular maintenance should be performed every 50 hours of operation or at least once per season. This includes oil changes, spark plug inspection, and checking the cooling and fuel systems.
Basic maintenance such as oil changes, spark plug replacement, and flushing the cooling system can be done by most owners. However, for more complex issues or routine inspections, visiting an authorized dealer is recommended to ensure proper care.
Signs that the impeller may need replacement include reduced acceleration, unusual vibrations, or strange noises coming from the jet pump area. Inspect the impeller for physical damage or wear and replace it if necessary.
