I had a similar situation happen when I was about 13. In a 14ft aluminum with an older 25hp. Motor stuck in wide open throttle... Never once crossed my mind to shut the motor off. Instead I bounced off the dock, a sailboat and motor went swimming... Bummer for that guy for sure, but good on him for not trying to be a hero about saving the boat and risking other peoples lives...
