On Wednesday, a ship noticed flashing lights coming from the uninhabited Chuuk State Island in Micronesia and alerted the US Navy, Hawaii News Now reports.
A Navy aircraft crew then spotted the pair on the beach on Friday and gave their location to the Coast Guard in Guam.
The pair were then picked up and taken to the safety of a patrol boat.
When they were found, they only had limited supplies and no emergency equipment with them.

The Coast Guard first received a report about the couple's 5.5m vessel going missing on August 19.
The alarm was raised after the pair left Weno Island on August 17 but never arrived at Tamatam Island where they were expected the next day.
The week long search covered more than 42,000 square kilometres.
