I own a Bayliner reflexx, it has a merc sportjet 90. being that this is the first jet boat I've<br />owned I don't know much about it. I just bought<br />it, had it out 3-4 times no problem,the next time<br />I take it out dead battery!<br /><br />Buy new battery run it off and on all day no problem,shut it off for 10 minutes,try starting<br />dead battery. Whats up? I was told the stater<br />might be bad. but batterys keep dying HELP!
