Apparently with blue motors and offshore hand throttle split shifters, there is a neutral position rev limiter deal. He was in neutral and throttle forward and stuck which caused the the motor surge. Being inexperienced he revved the motor and then engaged reverse which didn't help and in a panic shifted forward. At that point shit is going down fast and wasn't in the right mind to shut it down. End result is the ramp. Shit happens, luckily nobody got hurt.
Now, can I make the augment that every thing needs foot throttles? Just saying, never did like hand throttles of any kind.
