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.
Claims18
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;
- a first sprayer nozzle;
- and
- a second sprayer nozzle, wherein 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 sprayer assembly for cooling an outboard motor of a marine vessel, the sprayer assembly comprising:
- a sprayer nozzle comprising a body that extends from a first nozzle inlet and terminates at a first nozzle outlet and a second nozzle outlet;
- and
- a sprayer mounting bracket comprising a body that extends from a first end to a second end,
- wherein a nozzle mounting hole is positioned proximate the first end and a bracket mounting hole is positioned proximate the second end,
- wherein the sprayer nozzle further comprises a hexagonal shoulder portion configured to locate the sprayer nozzle relative to the sprayer mounting bracket;
- wherein the sprayer mounting bracket further comprises a pair of nozzle locating prongs positioned adjacent the nozzle mounting hole, and wherein the sprayer nozzle further comprises a locating tab configured to fit between the locating prongs.
A sprayer assembly for cooling an outboard motor of a marine vessel, the sprayer assembly comprising:
- a sprayer nozzle comprising a body that extends from a first nozzle inlet and terminates at a first nozzle outlet and a second nozzle outlet;
- and
- a sprayer mounting bracket comprising a body that extends from a first end to a second end,
- wherein a nozzle mounting hole is positioned proximate the first end and a bracket mounting hole is positioned proximate the second end;
- wherein the sprayer nozzle further comprises a hexagonal shoulder portion configured to locate the sprayer nozzle relative to the sprayer mounting bracket;
- wherein the sprayer mounting bracket further comprises a nozzle access opening positioned between the first end and the second end.
An outboard motor configured to be coupled to a transom of 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;
- a first sprayer nozzle;
- and
- a second sprayer nozzle, wherein 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.
