We have a 2002 Bennington 20' with outboard 50 Mercruiser. Joy riding for the weekend then yesterday we took it out and our radio kept cutting out, especially every time the driver pushed button to raise our lower motor. After a bit, we started hearing beeping noises, and noticed the voltage was low. Eventually the motor stopped and we got a tow back in. We thought it might be the battery, it was old, we replaced it and nothing, it won't turn. Any ideas what might be wrong? Obviously we are new to all of this.
