Customer Question

I have a 1997 sea doo gtx. It runs but when I get up to about 40mph it bucks back down to 30mph and will not go any faster. It should be able to go full speed at about 60mph on full throttle. What could be causing this problem

Hi there,Try pulling the choke when it bogs down to see if it comes to life.If it does then you problem is the carbs need rebuilt and tuned. You should have a professional do this.They need to set pop off pressure and then adjust mixtures to get the right burn or you could risk melting a piston.
