Had the same thing happen to a new GTI130SE Ski this week.Light Vibration on first run . Less than 5 Hours. Was cruising at 20 and lost Jet Drive. No signs of debris in Jet. Max out at 5mph. Horrific Vibration. At Dealer Now.
Same thing happened to me yesterday. Pulled out a plastic bottle cap that was wedged in the impeller blades this morning.
