Abstract

A marine propulsion device has an internal combustion engine that discharges exhaust gases, a driveshaft housing that is located vertically below the engine, and a catalyst that is sandwiched between opposing castings of the device that face each other at a split-line. The exhaust gases flow through the catalyst parallel to the split-line.
