Need some Advice.  

My fishing buddy and I heading out to the lake yesterday and were in a hurry due to a storm heading that way in a few hours. We got the boat in the water and began fishing the banks around the ramp we put in at.  Then I happen to look down and water was coming up through the drain in the middle of the boat, at that time I knew exactly what happen I forgot to put the drain plug in.  Within a few stressful minutes we had the boat out of the water and began to let the water drain out. I checked the battery compartment in the back of the boat and all 3 batteries were underwater (2 for the trolling motor). Then I tried to turn on the bilge pump and it wouldnt pump in maual or auto, also my fishfinders wouldnt turn on.  The question is my trolling motor still works and my other electronics dont seem to and they were both in the same situation.  Any help or advice would be appreciated

If they were maintenance free batteries, or if the caps were on tight, should not have botherd the batteries. If they have caps, pop them off and check the water level in them. If it's no higher than the fill ring, no harm done. If a cell/several cells are over filled it weakens the electrolite. About the only thing you can do then is dump all the electrolite and replace it with new. The will shorten the life of the battery but should give you some service.

I was checking some batteries outside and left the caps of one, a good two day rain came and flooded the battery. I dumped it, refilled it and used it another 18 months

Normally, the electronics and bilge pump are run off the cranking battery, if yours is that way, your problem could just be all the water caused the wire/cable connections to go bad. Pull everything off the cranking battery, clean everything and put it back together. If you still have problems, use a voltmeter and isolate the problem. Just start at the battery and start following the voltage until you loose it.

Thanks for the help, im going to start tearing into to it tonight.  I will keep you posted on what I figure out.    

I sank mine last year the same way. As soon as I got pumped out every thing started to work again and has continued to perform normally.

I sank my old Champ 16 1/2 Super V about 5 years ago.  Pretty good too.   ;D

Once we got the water out of it I had no problems with the electronics working.  In fact, the wire leading to the auto bilge pump switch was broken which is what caused the "incident" to begin with.  

Maybe you've got a breaker or 2 on that boat that tripped or perhaps fuses blew.  

After a few days of cleaning all of the connections and letting everything dry out, all of my electronics began working again.  Im going to do my best to make sure this doesnt happen again.

Thanks For everyones help.
