hey guys new to this page but figured i give it a shot,went to the lake today and when i started up the ski started up fine no issues, as soon as i was making my way out the marine the ski started to lose power and accelaration, i got to another dock near where we were staying and checked to see if i had picked up any debris but nothing. so i decided to turn it on again started up normally but after a few seconds started shaking again and wouldn't accelerate. so went back and loaded the ski, mind you it only has 21 hours on it so its still brand new, any ideas what the problem could be? thank you.
