I posted a comment last year about this. Here is my dilemma. I have a 2012 G2574 with a Merc 250 supercharged. I have the dual battery set up installed from the factory.
It was fine the first couple times out. Then all of a sudden I when i go to start the motor all I get is clicking. After about 10 - 15 times moving he throttle, turning things on and off it would start.
I progressively got worse. All of last summer in order to start the motor I would have to go to the dual switch adn move to a single battery. Start right up.
I then switch to dual when running like always and no problem. Then I beach or just stop and try to start and I have to do the same thing again.
I Bought it from Munson Marine, IL and they sent me a new switch. Tried it and didnt work. They sent me a second switch and it didnt work.
I took it to a local marine dealer. They worked on it over 12 hours and never found the problem but it did work just for the weekend and then same problem came back.
Spoke to Munson and they didnt know what to say.
End of season I took it to Basa Marine, IL for winterizing, and check the problem. They couldn't isolate the problem. What they decided it it is the batteries that I have. They recommended I replace them as the "amperage may not be consistent"
I have 2 Interstate Sealed AGM Deep Cycle batteries.
I brought it over to their headquarters in Mokena IL. They tested them and fond nothing wrong with the batteries. They said that there could be intermittent amp change but couldnt find it in their tests. They did give me 2 brand new batteries. That was awesome!
since it is winterized I couldnt check them out.
So, Any of you experienced this before? Mercury Reps? Bennington mechanics?
I am hoping I dont have to bring it to Munson as it is about about 100 miles from my location.
Other than that this boat is awesome!
Help would be greatly appreciated.
Thanks,
Bennie
