Claims (1)
ューブ下希開口を経て水中に排出させ、低速運転時には
、エンジンの排気ガスをニゲシーストチューブの上部側
壁に形成した排気通路を経て大気中に排出させるように
した船外機において、上記ニゲシーストチューブを、そ
の上部周壁に螺旋状のパイプを埋込んで一体に形成する
とともに、そのパイプの一端を周壁の外面に開口させ、
他端を周壁の内面に開口させて上記排気通路を構成した
ことを特徴とする船外機。During high-speed operation, the engine exhaust gas is discharged into the water through the lower opening of the Nigesheath tube, and during low-speed operation, the engine exhaust gas is discharged into the atmosphere through the exhaust passage formed on the upper side wall of the Nigesheath tube. In the outboard motor, the above-mentioned Nigeshiest tube is integrally formed with a spiral pipe embedded in the upper peripheral wall thereof, and one end of the pipe is opened on the outer surface of the peripheral wall,
An outboard motor characterized in that the exhaust passage is formed by opening the other end into the inner surface of the peripheral wall.
