The NTSB's narrative final · quoted from the NTSB record

The pilot stated that he was flying over water at an altitude of 3,000 feet mean sea level when the engine began to lose power. He contacted flight watch and informed them of the situation. His efforts to restart the engine by applying carburetor heat and full mixture were unsuccessul. He said that engine power was regained just prior to ditching the airplane. He exited the airplane which sank soon after contacting the water. The pilot was rescued 18 hours later. A review of the Federal Aviation Administration Carburetor Icing chart revealed the conditions were conducive to serious carburetor icing at glide power. The pilot reported he did not recognize the symptoms of carburetor ice and that he should have applied the carburetor heat sooner.
