Hello everyone I have a 2006 Challenger 180 CS I kept the boat inside my garage, and flush it every time I used it!! I did change the battery thinking that would resolve the problem, I can ear a little buzzing noise like the starter over the engine area. I did start the boat about a month a go and everything was in working order but I left the battery switch in the ON position, when I try to restart the motor the battery was to weak, I bought the new one and now the engine won't start.
