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.

Abstract: This invention relates to an animated musical alligator which features movement while playing music. The object of the animated musical alligator is to provide an original, amusing toy and novelty item for adults and children, alike.
