I have a 115HP (1981)
I have a 115HP (1981) Chrysler and the volt meter goes down to 11.5 volts while under full throttle. Using a volt meter hooked to the battery I have determined that the battery is discharging while cruising. If you idle the boat or go under 2200 rpm the boat charges and the battery voltage slowly climbs. Is this normal?
