Abstract

DISCLOSED HEREIN IS A MARINE PROPULSION DEVICE WHICH INCLUDES A DRIVE SHAFT HOUSING HAVING UPPER AND LOWER HOUSING SECTIONS, AND IN WHICH THE UPPER HOUSING SECTION IS ROTATABLY SUPPORTED FOR MOVEMENT ABOUT A HORIZONTAL TILT AXIS BY OPPOSITELY EXTENDING TRUNNIONS WHICH ARE RECEIVED IN INWARDLY OPEN COAXIAL APERTURES IN SPACED SUPPORTING MEMBERS FIXED TO THE BOAT HULL. POWER IS TRANSFERRED FROM THE ENGINE OUTPUT SHAFT TO A DRIVE SHAFT BY A HORIZONTAL CROSS SHAFT WHICH IS ROTATABLY SUPPORTED IN COAXIAL RELATION TO THE TILT AXIS AND BETWEEN THE TRUNNIONS BY A GEAR CASE HAVING FIRST AND SECOND GEAR CASE SECTIONS. THE FIRST GEAR CASE SECTION IS FIXED TO THE BOAT HULL. THE SECOND GEAR CASE SECTION IS INTEGRAL WITH THE UPPER END OF

THE DRIVE SHAFT HOUSING. STEERING IS AFFORDED BY ROTATING THE LOWER DRIVE SHAFT HOUSING SECTION BY A STEERING LINKAGE WHICH INCLUDES A WORM WHEEL SECTOR ON THE LOWER HOUSING SECTION AND A WORM GEAR WHICH IS ROTATED BY A DRIVE WHICH INCLUDES A STUB SHAFT ROTATABLY SUPPORTED WITHIN ONE OF THE TRUNNIONS.
