The Lake County Sheriff's Office identified the two involved as a 46-year-old man from Washington and a 55-year-old man from Franklin Park.

Chopper 7 was over the scene just after 4 p.m., and flames could still be seen coming from the boat.

The 25-foot fiberglass hull powerboat burned for about 90 minutes before sinking, the sheriff's office said.

The U.S. Coast Guard of the Great Lakes said there was no known pollution associated with the explosion and fire.

The cause of the explosion is under investigation by the Illinois Conservation Police, and the boat was a total loss.

The Lake County Sheriff's Office Marine Unit and Illinois Department of Natural Resources also responded to the incident.
