the RPMs are the same at throttle and idle, but the bad one dies after only a few seconds of ideling. And then will not start until it sits for a long time. A friend told me to check the fuel selector valve but I don't know where that is. What do you think?
Yes, In fact I have taken it in now 3 times, they can't figure it out. They have a good rep as a sea doo dealership, but I am about to pull my hair out. Could the drive train be stripped? but that would not cause it to stall or go for a while then spin out?
