Yesterday was out surfing and had PP set at 9.6. Everything is fine and then all of the sudden BAM the boat stops instantly. It was like someone just completely cut all power. I am surfing behind and realize what has happened and have to bail hard right to avoid hitting the back of the boat. Checked with the driver and throttle was still buried and he insists he didnt touch a thing. Still power to the boat. Just had to turn the key and it started right back up.

Very same thing happened to me the day before when I was on the back ... actually grazed the back corner of the boat.

Also happened again once before a few weeks ago when I was driving and my wife was on the back. It has only ever happened when surfing ...

Any idea what this could be??? It freaks you out a little knowing that at anytime the boat could stop and you have to be ready to bail. I'm just terrified that it will happen when we have someone up there who is just starting out and they smack their head off the back of the boat.
