Exhaust temperature – the first indicator of cooling failure

A blockage in the engine water intake or a damaged pump impeller will result in complete loss, or severe reduction in the volume of cooling water in the exhaust system. In this case the temperature of the exhaust will rise much faster than the temperature of the engine. We recommend that a exhaust temperature alarm is always installed in the exhaust line as it is a relatively small investment that prevent serious damage to all parts of the exhaust system in the event that raw water flow stops or is significantly reduced.
