Midsection housing for an outboard motor with water-cooled mounts

摘要

A midsection housing for an outboard motor includes a driveshaft housing having an oil sump provided therein. An adapter plate is coupled to a top of the driveshaft housing. The adapter plate has an inner surface along which oil from an engine mounted on the adapter plate drains into the oil sump. First and second pockets are formed in an outer surface of the adapter plate on first and second generally opposite sides thereof, the first and second pockets configured to receive first and second mounts therein. A water jacket is formed between the inner and outer surfaces of the adapter plate. The water jacket extends at least partway between the inner surface of the adapter plate and each of the first and second pockets, respectively. A method for cooling a mount is also provided.

1. A midsection housing for an outboard motor, the midsection housing comprising:
a driveshaft housing having an oil sump provided therein; an adapter plate coupled to a top of the driveshaft housing, the adapter plate having an inner surface along which oil from an engine mounted on the adapter plate drains into the oil sump; first and second pockets formed in an outer surface of the adapter plate on first and second generally opposite sides thereof, wherein each of the first and second pockets is defined by a respective inwardly concave arc in the outer surface of the adapter plate and the first and second pockets are configured to receive first and second mounts therein; and a water jacket formed between the inner and outer surfaces of the adapter plate; wherein the water jacket extends upwardly at least partway between oil-wetted portions of the inner surface of the adapter plate and each of the first and second pockets, respectively; and wherein the water jacket extends upwardly along at least 25% of an arc length of each respective arc of each of the first and second pockets.
