ABSTRACT:
A number of embodiments of treating the exhaust gases of an internal combustion engine with a catalyzer so as to render lubricant in the exhaust gases in a non-polluting form. A number of embodiments applying this principle to marine propulsion units are illustrated and described which include outboard motors and inboards. In each embodiment, the catalyst is position so that the exhaust gases will impinge upon it but need not flow through it for their discharge to the atmosphere. In addition, the exhaust system is designed in such a way that the catalyst may be removed and replaced simply by the use of a removable wall section of the exhaust system.
