The temperature indicator is one of the important methods used in determining faults in marine vehicles. If we talk about how to determine the fault thanks to the temperature indicator and what to pay attention to. It is extremely important to detect many faults correctly. It enables these faults to be repaired in a short time and to be more easily intervened. If the temperature gauge is on the red hand, the alarm sounds or the warning lamp is on, the gas must be cut off immediately. Also, you should slow down your boat and avoid sharp maneuvers. After that, you have to stop at a suitable place and anchor your boat. When you encounter this problem, you should first think of the situation where water congestion may occur. In such cases, the steps you need to follow are as follows;

• You must restart the engine first.

• The gearshift lever must be brought back.

• Start your boat by giving gas to your boat.

While doing this, watch the temperature indicator and repeat this process several times. If the needle drops when you complete this process, the problem is water congestion. If the problem is not resolved, another situation occurs.
