How to change sparkplugs on 2002 Yamaha waverunner fx140 4 stroke
Can anyone give me a quick guide on how to change the spark plugs? Plz
My waverunner is starting up fine and when out of the water it sounds great. When I place the craft in the water, the RPM go high, but speed does about 3 MPH.. I'm thinking I need to replace spark plugs?? If anyone could help thanks..

I would say its not the plugs. Look in your pump and see whats in there!
