NTSB Narrative Summary Released at Completion of Accident

The airplane was ditched in the ocean following a partial loss of engine power. During the initial descent into the destination airport, the pilot noted a "faint rumble and then the manifold pressure and rpm reduced very smoothly." He changed fuel tanks, turned the fuel pump into the "ON" position, and "moved" the throttle; however, full engine power was not restored. The engine was idling about 1200 rpm, the oil pressure gage indicated 40, and the fuel pressure gage was indicating normal. The pilot transmitted a "Mayday" call. He continued to troubleshoot the problem by turning the ignition to the "OFF" position, then to the "ON" position. The manifold pressure and rpm did not change. After securing the ELT and a life vest, the pilot opened the canopy when the airplane was approximately 200 feet asl. The airplane impacted the ocean at 50 knots. The pilot then swam out to the tail of the airplane. The airplane sank in about 3 minutes.

NTSB Probable Cause Narrative

the engine lost partial power for undetermined reasons.
