The recommended fuel type for the Yamaha FZS Waverunner 2012 is regular unleaded gasoline with a minimum octane rating of 86.
It is recommended to check and replace the spark plugs every 100 hours of operation or annually, whichever comes first.
To winterize your Yamaha FZS Waverunner 2012, thoroughly clean and dry it, add a fuel stabilizer, flush the cooling system, lubricate moving parts, remove the battery, and store it in a cool, dry place.
Check the battery connections and charge, inspect the fuel and spark plugs, ensure the safety lanyard is attached, and check for any error codes on the display.
Flush the engine with fresh water, clean the exterior, apply anti-corrosion spray to metal parts, and check for any salt deposits around the engine and hull.
To check the oil level, ensure the Waverunner is level, remove the dipstick, wipe it clean, reinsert it without screwing it in, and then remove it to check the oil level.
Store the Waverunner indoors on a trailer with a cover, ensure it is clean and dry, disconnect the battery, and make sure all maintenance is up to date.
Maintain steady speeds, ensure the engine is well-maintained with clean spark plugs and air filters, and reduce excess weight on the Waverunner.
Stop the engine immediately, check for water flow from the cooling system, inspect the intake grate for debris, and allow the engine to cool down before restarting.
To replace the battery, remove the seat, disconnect the negative terminal first, then the positive, remove the old battery, install the new battery, and reconnect the terminals starting with the positive.
