An exhaust gas purifying system of an engine (1) in a marine vessel comprising: an engine (1); a water generating machine (21) for changing a sea water to a real water; a water tank (22) for reserving the real water produced by the water generating machine (21); the engine (1), the water generating machine (21), and the water tank (22) being loaded in the marine vessel; an NOx included in an exhaust gas of the engine being purified by spraying (15) a reducing agent water solution to a reducing catalyst (10) provided in an exhaust pipe (8) of the engine; and the reducing agent water solution being manufactured by mixing a raw material reducing agent in solid-state, such as a powder state or a granular state, with the real water, wherein the exhaust gas purifying system has a raw material hopper (24) in which the raw material reducing agent is thrown, and a mixing tank (25) with agitating means (38) for mixing the raw material reducing agent discharged from the raw material hopper (24) with the real water so as to form a water solution, the water tank (22) and the mixing tank (25) are connected by a raw water conduit line (27), and a water solution conduit line (29, 31) leading the reducing agent water solution to the reducing catalyst (10) is connected to the mixing tank (25).
