Abstract
A coolant management system for a marine propulsion device provides a cavity within a driveshaft housing into which an oil reservoir is disposed. A water pump draws water from a body of water and causes it to flow through various coolant passages of the marine propulsion device. After passing through these coolant passages, the water is directed through a series of containments and compartments so that the level of water within the driveshaft housing varies in depth as a function of the operating speed of the internal combustion engine. This variance in depth causes a varying degree of cooling of the oil within the oil reservoir or sump.
