They were the combination deep cycle/cranking group 27 I think

I have the same problem, 5 batteries look under sized, I have to use the crossover switch to start the starboard engine and the port turns over kind of hard. All are reading 13.3 volts but don't seam to have the cranking power. When looking at group 31 is there a cold cranking amperage I should consider? There is a Sears Die Hard that has almost 700 CCA for $145.00
How do you guys get into the port side area where the batterys are? I don't have any problems with my batterys but want to get in there. I've been getting my boat ready for it's cruise home and absolutely can not squeeze in. I ended up changing port racor by laying on the metal floor support and reaching underneath, could not reach the gen racor at all. Is it because I'm old, stiff as aboard, and a little wide in the middle or are all you guys midgets?
Correction to above. The batteries were group 31They were the combination deep cycle/cranking group 27 I think
You'll find a splitter behind your electrical panel that distributes the signal. You're electrical panel swings out quite easily after removing a couple of screws to reveal a large space with several components.
Just ordered 4 of them, OUCH !Guys ,
Sears Platinum Marine AGM batteries. Look at the specs . These things are monsters.

Thanks for the letting me know Matt, I'll get a new AGM ASAP! Hopefully it's not a mess when I get back to the boatJ.Wilt,
I did the same thing a few years ago. I did not replace the generator battery with the agm. It trashed the lead acid battery. I checked on it a few days later and the genny would not start. When I checked the battery it had leaked all over, the only thing that saved me from a real mess was the battery box. YMMV but I would sped the money and make sure they are all agm. It has to do with the smart charger charging two different types of batteries.

I replaced the port side alternator on my 6CTA. It was quite easy. Three bolts to remove the belt guard. Then a 1/2 inch breaker bar onto the belt tensioner to turn it to loosen pressure on the belt and remove the belt. Then just a couple of bolts to remove the alternator. Rather than have mine rebuilt, I bought a new one from Seaboard Marine (sbmar.com) and based on recommendations here and at boatdiesel.com, I went with a 160amp version rather than the factory 135amp version.I replaced the generator battery with a new AGM so now they all match, after a couple days the acid battery was not as bad as Matt described, just a little wet on bottom of the battery tray. Glad it was not a mess when I got to the boat Friday.
Now on to my next item to get fixed, my Port side alternator that is not putting out proper voltage. I would like to remove it and take it in to be tested or repaired.
Have any any of you guys remove the port alternator? How hard of a job is it? Any tips would be helpful.
Thanks!
