摘要： The present invention is a system for air supply to the engine of a motor float comprising a bottom part and an upper part of the body defining the inner space of the float, in which a combustion engine is arranged, wherein the upper part of the body is in its front part provided with an air supply, characterized in that the combustion engine is arranged in the engine compartment and separated from the rest of the inner space of the float by means of a partition provided with a suction opening in its front part, wherein to provide the circulation of air in the inner space of the float a sealing rib extends from the front part of the partition towards the tip of the float, separating the air supply and suction opening from one another, wherein at least one rear pump for sucking the leaking water is arranged in the rear part of the inner space of the float. The main object of the invention is thus to use the interspace of the float to provide separation of water and air, when eventual separated water may be sucked away by a pump operating on any principle (electric, vacuum, etc.).

摘要： A water cooled four-cycle outboard motor having an improved flushing system that permits flushing of the cooling system without removal of even the protective cowling and which permits flushing to be accomplished with a minimum of water usage. The flushing connection is coupled with a tell tale connection to provide a simple, but highly effective construction. In addition, the system effectively cools the engine and a temperature sensor is positioned in an area where it will be protected from overheating.

摘要： A two-cycle, multi-cylinder engine maintains roughly equal temperatures between cylinders, despite differing exhaust efficiencies between the cylinders. Several ways of reducing the temperature of one of the cylinders in comparison to the other are disclosed. One embodiment involves supplying more coolant to the cooling passages around the hotter running cylinder. Other ways involve reducing the compression ratio or retarding ignition timing in the hotter running cylinder in comparison to the other cylinder.

摘要： Two embodiments of exhaust systems for small watercraft that include cooling jackets circling a portion of the exhaust conduit. At least a portion of the water from the cooling jacket is mixed with the exhaust gases but at a point spaced substantially downstream of the cooling jacket so as to reduce the likelihood of water entering the engine through the exhaust system. In one embodiment, an additional cooling jacket is provided to which the coolant from the first cooling jacket is introduced and then discharged into the exhaust conduit. The second cooling jacket is disposed substantially downstream of the first cooling jacket.
