Hello All,<br />I just purchased a 19' bass boat with the Merc 150 XR6 outboard. The motor is a 1992. My question is, does it have an alternator? Is it supposed to charge the starting battery while it is running, or do I need to charge it every once in a while. Seems to me that it must have some sort of charging system because of all the accessories that battery also runs.<br /><br />If there is one, it is not working. The battery is brand new and should be good (I guess I am assuming that). I just bought it a month ago. When I use a trickle charger, the boat starts great, but after a couple of weeks of use, the battery goes dead again. Last night I was on the lake fishing and it would not start. I had to move the wires over to one of the trolling motor batteries to get it going.<br /><br />If it is bad, does anyone know what it takes to replace it? I'll get the battery checked just to make sure.<br /><br />Thanks to the great board.<br /><br />Aaron
