JUST PRIOR TO THE ACCIDENT, WITNESSES OBSERVED THE VEHICLE FLYING OVER THE CENTER OFA LAKE AT APRX 250 FT & AT HI SPEED. REPORTEDLY, IT ENTERED A RIGHT BANK, WHICH CONTINUED, AND SUBSEQUENTLY, THE VEHICLEDESCENDED & STRUCK THE WATER IN A NOSE 1ST ATTITUDE. AN INVESTIGATION REVEALED THAT ON AT LEAST 2 OCCASIONS, AN OUTBOARDENG HAD INADVERTENTLY SHUT DOWN, INFLT. A FRIEND OF THE PLT HAD FLOWN THIS SAME VEHICLE & HAD EXPERIENCED AN OUTBOARD ENG SHUTDOWN. HE CONFIRMED THAT FULL OPPOSITE RUDDER WAS REQUIRED TO MAINTAIN CONTROL. ALL PROPELLERS WERE FOUND BROKEN,EXCEPT #4 WHICH WAS NOT DAMAGED. FLEXIBLE FUEL LINES WERE FOUND INSERTED IN THE FUEL TANK TO PICKUP FUEL FOR THE #1 & #4ENGS; HOWEVER, THEY WERE NOT SECURED TO ASSURE PROPER DEPTH.
