ール装置。A tube is loosely fitted to the drive shaft, and the tube is connected between the water pump housing and the drive shaft housing, and a portion of the cooling water sent out from the water pump is driven through the water channel between the tube and the drive shaft. In an exhaust gas sealing device for a cooling channel in an outboard motor, the exhaust gas is discharged from the shaft housing to the outside, thereby preventing exhaust gas from being mixed into the cooling water sent from the water pump to the engine.
A flange portion is formed by stamping at both ends of the tube, and the end portion of the tube is fitted into the water pump housing and the drive shaft housing through a sealing collar, respectively. Exhaust gas sealing device for cooling channels in outboard motors.
