ABSTRACT:
An improved exhaust probe arrangement within an exhaust system of a small watercraft increases the accuracy of the probe's readings. The aperture 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 aperture is generally unimpeded by the cooling water. The tendency of water to enter and clog the aperture is also reduced. The precision of the exhaust probe measurements consequently is greatly increased.
