How do I properly flush the engine of my Yamaha EX Waverunner after saltwater use?

To flush the engine, first ensure the Waverunner is securely on a trailer or stand. Attach a garden hose to the flushing port. Start the engine and then turn on the water. Let it run for about 10 minutes, then turn off the water before stopping the engine. This helps prevent salt buildup and corrosion.

What type of fuel is recommended for the Yamaha EX, EX Sport, and EX Deluxe models?

These models are designed to run on regular unleaded gasoline with a minimum octane rating of 87. It's important to avoid ethanol blends over 10% to prevent engine issues.

How can I troubleshoot starting issues with my Yamaha EX Waverunner?

If your Waverunner won't start, check the battery connections and charge level. Inspect the fuel level and ensure the fuel is fresh. Examine the spark plugs for wear or fouling. If these steps don't resolve the issue, consult a Yamaha technician.

What is the proper way to store my Yamaha EX Waverunner for the winter?

To winterize your Waverunner, begin by cleaning it thoroughly and draining any water from the hull. Add fuel stabilizer to a full fuel tank, and run the engine briefly to circulate the stabilizer. Remove the battery and store it in a cool, dry place. Cover the Waverunner with a breathable cover.

How do I adjust the trim on my Yamaha EX Deluxe for optimal performance?

The Yamaha EX Deluxe features electronic trim control. Adjust the trim up for higher speeds and smoother water conditions to lift the bow and reduce drag. Trim down in rough conditions to lower the bow for better control.

How can I improve fuel efficiency while riding my Yamaha EX series Waverunner?

To improve fuel efficiency, maintain a steady throttle and avoid sudden accelerations. Ensure the Waverunner is not overloaded and remove any unnecessary weight. Regular maintenance, such as keeping the engine well-tuned and the hull clean, also contributes to better fuel economy.

What is the break-in procedure for a new Yamaha EX Waverunner?

For the first 10 hours, avoid operating at full throttle. Vary the engine speed and avoid prolonged idling. After the initial break-in period, schedule a service to check the engine and change the oil. Following these steps ensures optimal engine performance and longevity.

Can I tow my Yamaha EX Waverunner behind a boat?

It is not recommended to tow a Waverunner behind a boat as it can cause water ingestion into the engine. If towing is necessary, use a tow valve to prevent water from entering the exhaust system and keep speeds below 5 mph.
