Abstract
A lubrication system of an outboard motor delivers lubricant to an internal combustion engine. The internal combustion engine is supported by an upper end of a case. The lubrication system has an oil pan configured to hold lubricant oil. An oil conduit has a lower end opening to the oil pan. An upper end of the oil conduit extends towards the internal combustion engine. An oil pump delivers the lubricant oil towards the internal combustion engine through the oil conduit. The oil pump is located in the vicinity of a front part of the oil pan as viewed from the side of the outboard motor. An inside bottom surface of the oil pan defines a lower bottom portion and an upper bottom portion. The lower bottom portion is located under the lower end of the oil conduit. The upper bottom portion of the oil pan is positioned rearward of the lower bottom portion.
