Re: Gauge on boat?
IOt would help to know what the numbers on the gauge are. It may be a water PRESSURE gauge in which case it would read 0 - 30 or 0 - 15. If it is a water TEMPERATURE gauge then it would read 100 - 240, 60 - 240, or some similar combinatiion. If it reads C - N - H that stands for Cold, Normal, Hot. You can figure that one out.
