Abstract

A combination cooling/filtration device is for cooling and filtering lubricant in an outboard motor. The device includes a body; a lubricant cooler configured to cool the lubricant, the lubricant cooler having an inlet port that receives cooling fluid and an outlet port that discharges the cooling fluid; a filter configured to filter the lubricant; and a lubricant passage extending through the body. The lubricant passage is configured to convey the lubricant from upstream to downstream, and in particular to the lubricant cooler, then to the filter, and then to an engine of the outboard motor. The body is axially elongated from top to bottom, the filter is mounted on the top of the body, and the lubricant cooler is located in the body below the filter.
