Abstract
The present invention provides an engine holder structure for a four-cycle outboard motor such that rigidity of an assembled engine can be increased with a simple structure. In accordance with the present invention, the shaft center of a drive shaft 10 is disposed offset from the shaft center of a crankshaft 4 with an outboard motor where an engine 3, mainly composed of a crankcase 25, a cylinder block 24 and a cylinder head 23, is mounted on an upper portion of an engine holder 2, a lower portion of which an oil pan 5 is fixed to; a crankshaft 4 is disposed substantially vertically inside the engine 3; and the rotation of this crankshaft 4 is transmitted to a propulsion device via a drive shaft 10.
