Fully plausible, as I have seen it on a V8 powered direct drive inboard boat. The exhaust flapper was defective...errr missing, and it back flowed into the engine immediately seizing it. The event happened as they came to a stop from speed. Required a complete motor overhaul, as it was salt water.
Although on an outboard I am not so sure I understand how? Plus that looks like it locked up at around 2,000+ RPM. Breaking hardened steel connecting rods usually takes more than a failure at idle. Laughingly I have seen many offroad vehicles suck water in and shut down to be cleared out, started back up, and continue down the trial.
