Exhaust and control for watercraft engine |
摘要 |
A watercraft has an exhaust system. The exhaust system has a first portion cooled by cooling jackets and a second portion cooled by merged flow. The first portion is coupled to the second portion with a flexible coupling having an undulating surface. An overheat detection system is positioned proximate the flexible coupling. The overheat detection system is arranged to detect a rapid increase in temperature resulting from a blocked cooling jacket. During periods of normal operation, a first temperature reading is detected. During periods of abnormal operation, a rapid increase in temperature indicates a sudden decrease in cooling water within the cooling jacket. Warning signals are emitted to the operator by an overheat prevention unit to advise the operator of the condition.
