Location: menasha wi 54952 | Your battery on a motor that old will not charge at low idle. You will need to up the RPMs to get the stator on the motor to put out more than 12.4 volts. Does your locator/graph display voltage? You can monitor how much voltage your outboard is putting out while at idle vs. higher RPM. Also, your battery at full charge without any load, should read about 12.2 - 12.4 volts. If it is less than that, lets say 11.8 or less, the battery is going bad. You may have an open cell that is allowing you to charge but no reserve to run for long periods of time. Just went through this with mine. Ended up being a bad battery.
