What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
N21890 departed tpf and landed at lal to pick up a passenger. After approximately 30 minutes on the ground at lal, N21890 departed lal, enroute to gvl. During climbout, the pilot noticed that his EGT was indicating 1600. The pilot continued his climb and enriched the mixture, which cooled the EGT to around 1550. Prior to reaching 4000 feet, the pilot noticed a mist on the lower part of the windshield. Not being sure wheather or not the mist was just moisure, he continued the climb to 4500. A few minutes after reaching 4500, now approximately 15 minutes into the flight, the pilot decided to return to tpf. The pilot maintained 4000 ft until near tpf, base leg for 4 was started at 1500?. At about 1000, over the water, the pilot began to increase the throttle. At that time, the engine did not appear to be producing power and the prop was windmilling. The pilot put the throttle, prop and mixture controls full forward, which had no effect. The pilot retracted the landing gear and prepared for a water landing. The pilot said that when he began his descent, the engine appeard to be running normal. He also said that during the flight, fuel flow was 19 -25 gph (normal). The only indication of a problem was the EGT at 1600 and the mist developing on the winshield.
After landing in the water, approximately .7 nautical mile from the approach end of runway 36 at tpf, both occupants exited the aircraft. The aircraft sunk in 10-15 feet of water.
The aircraft was inspected after being taken out of the water. There was lower cowling damage on both sides of the aircraft. Aft of the foot step, approximately 4 feet of the underside of the fuselage was opened, which also revealed beent ribs and supports. The throttle, prop and mixture controls were found full forward, gear lever in the up position. The fuel valve was in the off position. The pilot said he did not touch the fuel valve. It is believed to have been turned off by one of the dive team members that floated the aircraft.
The inspection at the scene or interview with the pilot did not indicate the pilots action of inaction contributed to this accident.
Inspectors from orlando FSDO SO15 will respond to jacksonville to inspect the aircraft further. This report will be amended when a determination is made as to what caused the engine to lose power.

PRIOR TO REACHING 4000 FEET, THE PILOT NOTICED A MIST ON THE LOWER PART OF THE WINDSHIELD. NOT BEING SURE WHEATHER OR NOT THE MIST WAS JUST MOISURE, HE CONTINUED THE CLIMB TO 4500. A FEW MINUTES AFTER REACHING 4500, NOW APPROXIMATELY 15 MINUTES INTO THE FLIGHT, THE PILOT DECIDED TO RETURN TO TPF. THE PILOT MAINTAINED 4000 FT UNTIL NEAR TPF, BASE LEG FOR 4 WAS STARTED AT 1500?.
