ABSTRACT:
An internal combustion engine of the type utilized to power an outboard motor and having a cooling arrangement for reducing the transmission of heat from exhaust gases flowing through an exhaust passage from the engine to the combustion chambers of the engine, is disclosed. In general, the cooling arrangement comprises an air-filled space formed in the cylinder block between the combustion chambers and the exhaust passage. In a first arrangement, when the engine is of the in-line variety and the combustion chambers are vertically arranged, air spaces are formed between a common vertically extending exhaust passage leading to an exhaust pipe, and each combustion chamber. In a second arrangement, when the engine is of the "V" type, an air space is formed in the portion of the cylinder block defining the inside wall of each cylinder bank, between each combustion chamber and a common exhaust passage extending through the valley between the cylinder banks.
