ABSTRACT:
An arrangement of an exhaust gas collection port within an exhaust system of a small watercraft increases the accuracy of an associated probe's readings. The port is located upstream of a point where cooling water is introduced into the exhaust system for silencing purposes. As a result, the ingress and egress of exhaust gases flow into and out of the port is generally unimpeded by the cooling water. The tendency of water to enter and clog the port is also reduced. The precision of the associated exhaust probe measurements consequently is greatly increased.
