Claims

[Scope of utility model registration request]

A drive shaft that is connected to the engine crankshaft and drives the propeller shaft is installed in the hollow part of the extension case that is attached to the lower surface of the engine body, and a water pump that extends from the discharge port of the water pump that is driven by the drive shaft. In a water cooling system for an outboard motor in which a water pipe is installed and the water pipe is connected to a water supply channel formed in the engine body and connected to a water jacket, a mounting hole is formed in a support plate interposed between the engine body and an extension case. The upper end of a grommet-like elastic joint that is bored and installed in the mounting hole is tightly fitted to the water supply channel, and the upper end of the water supply pipe is tightly fitted to the hollow part of the elastic joint. Machine water cooling system.
