るものが提案されている。[Prior Art] Generally, a marine propulsion device having a water-cooled engine;
In particular, water injection type marine propulsion devices use a jet of seawater or the like to send cooling water into the engine, so it is necessary to clean the water jacket of the engine after use. In this case, conventionally, the cooling water hose or pipe connected to the engine's water jacket was removed and clean water such as tap water was sent from that part to the water jacket to clean it, but the cooling water hose, etc. was attached. , the removal work was complicated and difficult, so for example,
As described in Publication No. 68120, a cleaning water supply port is provided in the engine water jacket, and a check valve is installed in this cleaning water supply port. A system has been proposed in which a water jacket can be cleaned simply by connecting a cleaning hose such as a water hose to a supply port.

に設けられている。 The engine 14 mainly includes a cylinder block 30,
cylinder head 32 at the top of the cylinder block;
Crankcase 34 at the bottom of the cylinder block,
Exhaust expansion chamber 3 located above the cylinder head
6, and an exhaust passage 38 connecting the exhaust port (not shown) of the cylinder block and the exhaust expansion chamber.
A crankshaft (not shown) is located inside the crankcase 34, and is connected to the propeller shaft 18 via a coupling ring 40. In addition, the code 48
5 is a spark plug attached to the cylinder head 32, and 50 is an anti-vibration damper that supports the engine. A well-known water jacket 42 is formed within the cylinder block 30, and the downstream side of this water jacket 42 communicates with the exhaust expansion chamber 36. Therefore, in this embodiment, the cooling water in the water jacket 42 joins the exhaust gas of the engine in the exhaust expansion chamber 36, and is discharged from the exhaust port 46 formed in the outer wall of the hull 10 via the exhaust pipe 44. It's summery. The upstream side of the water jacket 42 is connected to a first cooling water hose 52, which passes through the partition plate 19 via a joint 53 and is connected to a second cooling water hose outside the boat. This second cooling water hose 56 is connected to a cooling water hose 56, and this second cooling water hose 56 is connected to the outside of the boat, that is, the engine room 1.
1 and is connected to a water intake port 58 bored in the casing 22 that houses the impeller 20 via a connecting member 60 that will be described later. The water intake port 58 is located behind the impeller 20,
That is, the opening is opened at the position of the guide vane 21, so that water, which is pressurized by the rotation of the impeller 20, is introduced into the water jacket 42 through the water intake port 58 or the cooling water hoses 56, 52. There is. As shown in FIGS. 3 to 5, the connecting member 60 has a hollow, substantially cylindrical main body 62 and a branch pipe 64 integrally formed in the substantially center of the main body. It is screwed into the water intake port 58 of the casing 22 at a position behind the impeller. One end or front end 62 of the main body 62
The second cooling water hose 56 is connected to A,
Thereby, the inside of the casing is communicated with the second cooling water hose 56. The other end, that is, the rear end 62B of the main body 62 is a wash water inlet, and a plug 66 is removably screwed into the wash water inlet 62B. Note that the front end 62A and the rear end (washing water inlet) 62B are coaxially penetrated, and are denoted by reference numeral 6.
3 is a stepped portion provided in the middle of the penetrating portion.
Specifically, the plug body 66 has a male thread 68 that is screwed into the male thread of the rear end 62B of the main body 62, and the screw can be easily removed by the user from the outside. A grip portion 70 is provided to allow the user to hold the camera. That is, the cleaning water inlet 62B, which is the rear end of the connecting member 60, and the gripping part 70 of the stopper 66 attached to the cleaning water inlet
is located toward the rear of the ship, as shown in FIG. 2, and is therefore within easy reach of the user.

４２に導入される。 When the connecting member 60 is in the state shown in FIG. 3 and FIG. water (see figure) is sucked in, the pressure is increased by the impeller 20, and the water is injected to the rear of the ship from the steering nozzle 23, and is also sent from the water intake port 58 to the connecting member 60. Since the cleaning water inlet 62B of the connecting member 60 is closed by the stopper 66, water is sent from the branch pipe 64 to the second cooling water hose 56, and is supplied to the engine 14 via the first cooling water hose 52. It is introduced into the water jacket 42.

is connected to the cleaning water inlet 62B, which is the rear end of the connecting member, via the connecting fitting 82. Here, the connecting fitting 82 is inserted to a position where its tip almost abuts the stepped portion 63, and is fixed by being screwed into the female thread of the rear end 62B of the connecting member at the male threaded portion 84 located approximately in the middle thereof. . As a result, fresh water from the cleaning hose 80 flows to the cleaning water inlet 62B,
Second cooling water hose 56, first cooling water hose 5
2 to the engine's water jacket 42, where it is cleaned and then discharged overboard via the exhaust pipe 44. Note that the branch pipe 64 is closed by a connecting fitting 82, as can be seen from FIG.

The only points are that instead of the grip part 70, there is a groove 71 for receiving the tip of a screw tightening tool such as a screwdriver, and that the screws of the branch pipe 64 and the water intake port 58 are eliminated and these are press-fitted together. It is.
Therefore, in this embodiment, a screwdriver or the like may be used to attach and detach the plug 66 to the main body 62 of the connecting member 60.
