ABSTRACT:
A device for sensing the presence of water within the exhaust manifold of a marine engine. A probe is provided having a first conductive element and a second conductive element operably extending into the main exhaust gas chamber within the exhaust manifold. Circuit means are provided having an input operably coupled to the probe for sensing and displaying a reduction in the effective impedance between the first and second conductive elements responsive to water being operably coupled therebetween.
