Abstract
A cooling system for an outboard motor of a marine vessel is provided. The cooling system includes an oil sump housing having an inner housing wall and an outer housing wall. The inner housing wall defines a transmission mounting cavity, and the inner housing wall and the outer housing wall defines an oil containment cavity that at least partially surrounds the transmission mounting cavity. The cooling system further includes a first sprayer nozzle and a second sprayer nozzle. Both the first sprayer nozzle and the second sprayer nozzle are coupled to the oil sump housing and configured to spray cooling fluid within the transmission mounting cavity onto an inner surface of the inner housing wall.

A cooling system for an outboard motor of a marine vessel, the cooling system comprising:
- an oil sump housing comprising an inner housing wall and an outer housing wall, the inner housing wall defining a transmission mounting cavity, and the inner housing wall and the outer housing wall defining an oil containment cavity that at least partially surrounds the transmission mounting cavity;
- and
- at least one sprayer nozzle coupled to the oil sump housing and configured to spray cooling fluid within the transmission mounting cavity onto an inner surface of the inner housing wall.
An oil sump housing for an outboard motor of a marine vessel, the oil sump housing comprising:
- an inner housing wall defining a transmission mounting cavity and having a horizontally-aligned portion and a vertically-aligned portion;
- and
- an outer housing wall spaced apart from the inner housing wall;
- wherein the inner housing wall and the outer housing wall define an oil containment cavity that at least partially surrounds the transmission mounting cavity such that oil that falls onto the horizontally-aligned portion of the inner housing wall flows into and is contained between the vertically-aligned portion of the inner housing wall and the outer housing wall.
An outboard motor for a marine vessel, the outboard motor comprising:
- a powerhead that causes rotation of a driveshaft;
- an oil sump housing located below the powerhead and comprising an inner housing wall and an outer housing wall, the inner housing wall defining a transmission mounting cavity, and the inner housing wall and the outer housing wall defining an oil containment cavity that at least partially surrounds the transmission mounting cavity;
- a transmission located within the transmission mounting cavity;
- and
- at least one sprayer nozzle coupled to the oil sump housing and configured to spray cooling fluid within the transmission mounting cavity onto an inner surface of the inner housing wall.
