Outboard engine assembly

摘要

An outboard engine assembly is provided for dividing an engine room into two room sections with a sealing property to protect an air intake system from being adversely affected with heat generated by an exhaust system. The outboard engine assembly has a wall means serving as a partition wall to divide the engine room into two room sections. The wall means has a profile formed in a thick string which is placed between an outer side wall of a cylinder head cover and an inner side wall of an engine cover. In one of the two room sections, the air intake system is located for supplying intake air to a combustion chamber of an engine from outside. In the other one of the two room sections, the exhaust system is located for expelling exhaust emissions outside from the engine.
