I have a 1996 Evinrude 175. It runs great but this past weekend on a ride I notice the voltage meter was high. On the fishfinder it showes a range of 14.5--17.9 volts. I had not used the boat in about 1 month. It sat with the bilge in auto during a very wet period. Is this a low battery pulling a bigger charge or is it somthing more severe?

The regulator should limit the voltage output to around 14.5 volts. This applies no matter how much current is flowing. It sounds like your voltage regulator unit has malfunctioned.

Check it with a good voltmeter. I have found that the meter in a SONAR is not always very accurate.

It's NOT the battery. The voltage regulators job is to
deliver a specific (temperature dependent in the better ones)
voltage. It will not go high. It could go low under some
circumstance (like a really large current draw).

I agree with jimh, first check the voltage with a good
voltmeter, if it's still high, replace the regulator.
