brand new deep cycle battery,, way too big for this motor to begin with, ,, ran great first few times out this year, now every time i go to the ramp i need a boost ,, then its fine all day has tons of amps,,can start and stop all day fishing no issues  What could be draining my battery when it sits for a week ?,, i dont have any electronics  im going to go unhook it now and charge it ,,i hope it starts tomorrow

I am guessing you don't hear a tiny buzzing noise that might be your bilge pump on constantly? |

I always thought that deep-cycle batteries were to run accessories, trolling motors and lights, etc. ... They will crank a motor, but it's not their designed use, perhaps prolonged use as a starting battery has killed a cell and shortened it's life. If it runs all day and holds a charge then I'd say your charging system is working properly. Can you throw a known good battery in it while it sits for a few days to rule out a bad battery? |

If you have one, I would say your rectifier. Had it happen to a 25 and 80 Merc. It's broken so it is grounding out to your motor and draining the battery. http://en.wikipedia.org/wiki/Rectifier |

You've got a short "somewhere" I would try that to see what's going on. replacing the battery without knowing what the problem is, could result in exactly the same thing happening again. Also - wasted money on a new - not required battery. |

Like Tom said leave the battery cable off until you figure it out. IF the battery still goes dead than it's the battery....or take the battery out and have it load tested. |
