Re: normal charging voltage 1986 70hp
I have the same engine. The charging system is unregulated, so the voltage will go hi when your battery is fully charged. The charging system is only 6 amps max though so there is little chance of boiling the battery. Probably a good idea to keep an eye on water levels in it anyway. I check once a month or so just to be safe. Most modern electronics can handle the hi voltage, but it would be a good idea to be sure of that when you buy new stuff.
