OIL PUMP STRUCTURE FOR ENGINE FOR OUTBOARD MOTOR

摘要

PROBLEM TO BE SOLVED: To provide an oil pump structure for an engine for an outboard motor wherein an oil pump is driven by a crank shaft without complicating the structure of an engine. SOLUTION: The oil pump structure for an engine of an outboard motor is formed such that an engine 20 is arranged in the engine room 9 of the outboard motor having the engine room 9 having a bottom partitioned by a guide member 17 with a crank shaft 21 vertically extending. In this case, an oil pump 100 for the engine is fixed in a position situated vertically below the crank shaft 21 of the engine 20 on the upper surface of a guide member 17 and the crank shaft 21 is coupled to an oil pump 100 such that the oil pump 100 is driven through rotation of the crank shaft 21. The oil suction port 111a of the oil pump 100 is opened to the bottom of the pump case 105 of the oil pump 100. An oil passage 17b to interlink the oil suction port 111a and an oil pan 83 arranged below the guide member 17 is formed in the guide member 17.
