The invention discloses a marine clutch. The clutch comprises a clutch body, wherein the clutch body comprises a first driving friction cone, a first driven friction cone, a second driving friction cone, a second driven friction cone, a shaft hub, an air distribution disc, a cover plate and a transition disc, wherein an air channel is formed on the air distribution disc; one side of the clutch body is connected with a gear box input shaft, and the other side of the clutch body is connected with a diesel engine flywheel; the side of the clutch body, which is connected with the diesel engine flywheel, is provided with a high-elasticity element between the clutch body and the diesel engine flywheel; a first diaphragm component and a second diaphragm component are arranged between the first driven friction cone and the shaft hub, and between the second driven friction cone and a spindle respectively; a cylinder is arranged among the first driven friction cone, the second driven friction cone and the shaft hub; and a bearing part is arranged between the shaft hub and the spindle. The high-elasticity element for shock absorption is independently arranged outside the clutch and is connected in series with the clutch, so that the radial space of the high-elasticity element is unlimited and can be arbitrarily determined according to the requirement, and the shock absorption function ofthe high-elasticity element is fully exerted.
