Voltage

[clasavi]

I have two batteries hooked up to the switch. One is a starting and the other is a deep cycle.

I noticed that when I am running the boat, the voltage meter on the dash reads over 18. Is this effecting the boat's performance?

Re: Voltage

It's burning up your batteries for sure, and will everntually burn up other things.
First check with a DVM at the battery and confirm that is the voltage going to the battery (you could have a faulty gauge at the helm).
If you actually are getting that kind of voltage, get your alternator tested and repaired.

What engine we working on ??????????

Fix known problems first, then see if you still have problems.
