Easy-to-clean outboard engine

The invention discloses an easy-to-clean outboard engine, which comprises a cleaning connecting mechanism, wherein the cleaning connecting mechanism comprises a rubber sling ring and a plastic water through part, the rubber sling ring and the plastic water through part are mutually fixed, the rubber sling ring is fixedly connected with a transition disc, and sleeves the periphery of the plastic water through hole, the plastic water through hole is provided with two connecting sections, the two connecting sections are respectively connected with an inner water pipe and an outer water pipe, the plastic water through hole is provided with an end surface, and the two connecting sections are respectively arranged at the two sides of the end surface. The easy-to-clean outboard engine has the beneficial effects that when the engine rotates, the pressure relief and water drainage functions of cooling water are realized by the cleaning connecting mechanism; when an engine user requires to service the engine, the user can utilize the cleaning connecting mechanism to conveniently clean the engine, a hood of the engine does not need to be opened, only an external water pipe is connected, the cleaning water flow reversely flows through a cooling water path through the outer water pressure, and the engine is smoothly cleaned; the structure is firm, the sealing property is good, and the service life is long.
