This dramatic clip show the moment NYPD divers jumped from their helicopter to rescue two men who’d been knocked out of their raft in Brooklyn.

The victims were on a rubber raft in Jamaica Bay near Floyd Bennett Field around 11:10 a.m. Friday when a 30-foot boat struck their vessel, causing it to overturn and tossing them into the water, cops said.

Video released by police Saturday shows scuba team members hurling themselves from an aviation unit chopper into the swirling waters, where they swam to the victims and provided medical attention.

They found a 62-year-old man unconscious with a large cut on his head. Cops hoisted him into their helicopter in a rescue basket, then rushed him to Staten Island University Medical Center, where he was listed in stable condition.

The NYPD’s harbor unit brought the second victim, an adult male, to Brookdale Hospital, by boat. He was in stable condition.

Detective Dylan Johnson and officer Jonathan Mcauley of the scuba team and officer Jeffrey Meagher of the harbor unit were involved in the rescue.

The operator of the 30-foot boat that hit the raft remained on scene and was not charged. Police brought both the raft and the boat to Canarsie Pier.

Cops said they continue to investigate the matter.
