A high output 2-cycle engine and a watercraft powered by the 2-cycle engine. The 2-cycle engine includes a crank case having a water jacket, and a cylinder block with a water jacket for cooling the cylinder block. Cooling water is supplied separately to the crank case water jacket and the cylinder block water jacket to increase cooling of the crank case and the cylinder block. The 2-cycle engine may be an air scavenging engine in which fresh air is supplied to the engine through the crank case, and fuel is injected into a combustion chamber by a fuel injection device. The cylinder head and the exhaust manifold of the engine may also include water jackets.
