Benefits of technology

The invention provides an outboard motor that cools the air compressed by a supercharger without getting the cowling of the motor bigger. It also includes a marine vessel with this outboard motor.

Problems solved by technology

In the outboard motor described in Japanese Patent Laid-Open No. 2011-226390, although the intercooler can be used to cool air (intake air) compressed by the turbocharger, the intercooler is disposed in the cowling, and hence the cowling is disadvantageously increased in size.
However, in order to further cool the compressed air, it is necessary to further increase the size of the intercooler, and hence it becomes more difficult to dispose the intercooler inside the cowling.

first preferred embodiment

[0036]The structure of a marine vessel 100 according to a first preferred embodiment of the present invention is described with reference to FIGS. 1 and 2. In the figures, arrow FWD represents the forward movement direction (front) of the marine vessel 100, and arrow BWD represents the backward movement direction (rear) of the marine vessel 100.

[0037]The marine vessel 100 according to the first preferred embodiment includes a vessel body 10 and an outboard motor 20 mounted on the vessel body 10, in which an engine 21 is mounted, as shown in FIG. 1.

[0038]In the marine vessel 100, the vessel body 10 is steered based on an operation of a steering wheel (not shown) performed by an operator. In the marine vessel 100, the output and shifting (forward movement, backward movement, or neutral) of the engine 21 of the outboard motor 20 are controlled based on an operation of a remote controller (not shown) performed by the operator.

[0039]As shown in FIG. 1, the outboard motor 20 is mounted on...

second preferred embodiment

Modified Second Preferred Embodiment

[0080]A modified second preferred embodiment of the present invention is described with reference to FIG. 5. In the modified second preferred embodiment, an intercooler 333 is mounted on an outer surface 22b of a cowling 22 of an outboard motor 320 unlike the second preferred embodiment in which the intercooler 33 is installed in the vessel body 10. In the modified second preferred embodiment, the same structures as those of the second preferred embodiment are denoted by the same reference numerals and description thereof is omitted. The intercooler 333 is an example of a “compressed air cooler”.

[0081]As shown in FIG. 5, the air-cooled intercooler 333 is installed as an element of a supercharging unit 330 in the outboard motor 320 of an outboard motor unit 301 according to the modified second preferred embodiment. Specifically, the air-cooled intercooler 333 is mounted on the outer surface 22b at a top 22a of the cowling 22 of the outboard motor 3...

Abstract

An outboard motor unit includes an outboard motor including a cowling and an engine housed in the cowling and that is mounted on a vessel body, a supercharger that compresses air, and a compressed air cooler that is installed outside the cowling of the outboard motor and cools air compressed by the supercharger.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of priority to Japanese Patent Application No. 2016-185975 filed on Sep. 23, 2016. The entire contents of this application are hereby incorporated herein by reference.BACKGROUND OF THE INVENTION1. Field of the Invention[0002]The present invention relates to an outboard motor unit and a marine vessel including the outboard motor unit.2. Description of the Related Art[0003]An outboard motor including a supercharger is known in general. Such an outboard motor is disclosed in Japanese Patent Laid-Open No. 2011-226390, for example.[0004]Japanese Patent Laid-Open No. 2011-226390 discloses an outboard motor including a cowling that includes an engine cover or the like. The outboard motor further includes an engine, an intercooler, and a turbocharger (supercharger), all of which are installed in the cowling.[0005]In the outboard motor described in Japanese Patent Laid-Open No. 2011-226390, although the intercoo...
