Kac...a reading of 11.5 after a couple hours of use does not mean anything. You have to let the batteries settle for at least an hour with no load before taking a reading. So..bottom line...they MAY be just fine.
As dawg says...T105 Trojans are excellent batteries and many cruisers prefer them to standard 12V batteries. For cruising, I personally like sealed AGM's and a much bigger bank so you'll need to think through your use and your needs on that score in the future. In the meantime...top the fluid up on the T105's if it is low nd leave it for a day or to while charging them fully...turn the fridge and everything else on for an hour...then turn everything off for an hour and measure with a hydrometer or a meter at the baterry terminals...hydrometer is most effective. If you don't come up with a good hyrometer reading or voltage in the mid-12's...chances are it is time for a replacement.

|Freesail99||You can also get crown batterys rated at 225 amps each for $170.00. THey can be found Here.|

Trojan T105 6VDC golf cart batteries are excellent batteries for the buck, and can take a lot of abuse... Two of them in series gives you about 225 Amp-Hours at 12 Volts. Not a huge amount of power, but not bad as a small house bank if you have relatively modest electrical needs.
Did you check the water level in the batteries.. if the water level is low, they can behave the way you're describing. IF the water level has been low for a while, the batteries are probably toast.

|ntheyer||The golf cart batteries are probably the most valued style for long term cruising. They can withstand discharges the best of all batteries out there. I would agree with you though that the one in the boat are toast. Not knowing what Amp Hour rating they have doesn't help knowing if they are ok, but no matter how small the battery could be, an hour or two of a stereo could never knock them down. They are shot. If you are looking at serious bluewater cruising, these are the best. Wire two six volt batteries in series to get twelve volts out.|

A lot of people swear by the 6v Golf cart type batteries.
Just because they are the 6V type does not mean they are ****.
Are you sure they were charged before you left?

Forgot to mention battries
I forgot to tell you about the batteries.
there is another potential issue...
I think the batteries might be ****. They are two deep cycle golf cart batteries.
Obviouly I would want more juice than golf cart batteries if I go offshore, so I would replace them, but, I do not think they are working fine as is right now anyway, this may be another reason to lower the price of the boat.
The batteries were fully charged when we went on the Sea trial. When we came back, 1 hour later, after just using the stereo, they were down a significant amount. from 13.5 V(when fully charged) to about 11.5 V
I do not know much about batteries, is this normal? We hardly used any power at all.
How much would replacements be?

Thanks for all the tips, will keep you guys posted.
Yes, I actually think the engine is 3GM The broker may have made a mistake listing it as 2GM.... in that case, I get more bang for my buck. But i am trying to be quiet about this lol

|sailh34||We just ordered a presized bimini from Overtons that was close to what we had on there before. We plan on just cutting it and resewing on reinforcing strips or a zipper where the backstay cuts through it. The bimini was 6 feet long x 8 feet wide. It came with an aluminum frame that was 54" high and it cost something like $330. We got Sunbrella, but had we gotten the lesser fabric (sharkskin), it would have been $250. Vinyl would have been even less. May be worth looking into if the current bimini is close to one of the prefab ones - check it out.|
