An outboard motor equipped with a water-cooled engine includes an exhaust manifold cooling water jacket for cooling an exhaust manifold for discharging to the outside exhaust gas from a combustion chamber, the exhaust manifold cooling water jacket being supplied with cooling water from a cooling water pump. A water outlet provided in the highest part of the exhaust manifold cooling water jacket is made to communicate with a water check outlet for confirming the circulation of cooling water due to operation of the cooling water pump. Thus, it is possible to reliably discharge air residing within the exhaust manifold cooling water jacket through the water check outlet. Since the water check outlet is used as an opening for discharging air, it is unnecessary to provide a special air outlet.
