Abstract
A marine outboard motor for a marine vessel is provided. The marine outboard motor includes an internal combustion engine, a drive shaft configured to transmit a drive force from the internal combustion engine, a propeller shaft, and a drive transmission configured to transmit the drive force from the drive shaft to the propeller shaft. The motor also includes a lubrication system configured to convey lubricant along a lubricant flow path to lubricate one or both of the drive transmission and the drive shaft, and a lubricant filter provided along the lubricant flow path and configured to remove solid contaminants from the lubricant as it flows along the lubricant flow path. The lubricant filter is configured to be driven by the drive shaft.
