PROBLEM TO BE SOLVED: To reduce a rise of an intake air system temperature due to heat at an engine side to suppress evaporation of fuel moisture, and to improve the restartability and the stability at low speed. SOLUTION: An engine for a pusher comprises an engine 10 in which each of cylinders is arranged in a longitudinal direction, and an intake air system communicating with a combustion chamber of each cylinder and provided in the engine 10. A cooling water channel is provided in the engine 10. Cooling water is sucked up by a water pump driven in linkage with the rotation of the engine 10. In this constitution, a heat insulator 400 is arranged between the engine 10 and the intake air system. |
