I bought the boat (2013 22'' SSLX with 150hp merc) new last spring and had zero issues all last season for about 50 hours of use. I stored the battery inside during the winter on a trickle charger. This spring, the boat worked great for about 6 trips then we got out on the lake and it would not start up. The engine would beep but would not crank at all. I could not get the battery to hold a charge even on a trickle charger, so I got it replaced under warranty and put the new batter in last week (Interstate Marine 800 CCA). The boat worked fine for another 3-4 times, but then started sluggishly and beeped at me on startup, and when I turned it off out on the lake, it died again and left us stranded for a second time.
So, either the battery is not being recharged properly by the alternator, or something is draining it while the boat is off. The stereo is off and the nav lights are off, and there is nothing else I can think of that could be draining the battery dead so fast? Any thoughts or suggestions?
