Five Ten Jet I Capsized A Jet Ski In Thailand And The Owner Says It's Broken - Is This Possible?

I capsized a jet ski in Thailand and the owner says it's broken - is this possible? - five ten jet

I stopped renting jet-skis. I used it for five minutes before returning to the beach (no problem). When he left the owner stopped me and told me it was broken. He played with the engine, as this Thailand and now I suspect a fraud, especially what has changed the price for the repair of a factor of ten when he said I had no money. So please, help me out - can damage the engine if the fear, and if so) how difficult (and expensive to repair. Any information would be greatly appreciated.
