Abstract
A personal watercraft includes a component arrangement which reduces heat exposure to many critical, heat-sensitive components of the watercraft. The personal watercraft includes a calalyzer within an exhaust system to treat engine exhaust before discharge. The catalyzer operates at a high temperature. Heat-sensitive components of the engine, such as, for example, fuel and coolant supply lines and electrical and mechanical cables, are positioned on a side of a longitudinal center line of the watercraft opposite of the catalyzer. This arrangement reduces the degree of heat exposure experienced by these engine components to improve their function and durability.
