so I plugged up my battery's last night around 7ish my step dad and mom was taking the boat out this morning (im at work) but when they got to the lake the trim would not work and the motor would not turn over..i have a triton 3 bank charger that says the battery's are charged...I was out on it last week on Friday and everything was fine but step-dad said the live well switch was left on when he got to the lake.....could this be a motor issue? or just battery? thanks  for all the info

Do they have jumper cables? If so, try jumping from a trolling motor battery to cranking battery. That should get them going and answer your question.

I will tell them to try it they are home now and but the battery's back and charge i will tell them to try that if it still don't work

just talked to them it was the battery it was completely dead had to put a bigger charger on it and not the trim is working thanks

Check the livewell pump(s) for damage as well, running that long out of the water could have weakened them.
