Mercruiser 377's with DTS & Axius - Battery Replacement options?

[pcmpete]

I am looking at replacing the batteries this year.
I have twin Mercruiser 377's with DTS & Axius.
My Express Cruiser currently has 4 batteries total from 3 different manufacturers. (from Previous owner)
The trays are set up for Group 27, but don't changing to Group 31 trays if needed.
My onboard charger can handle flood acid OR AGM.

According to Mercruiser, I need a minimum of 1000 MCA, 190 Ah batteries because I have DTS.
IF you have a similar setup what batteries would you recommend? (urls are be great).

Thanks

Deka makes a 27m6 that meets your needs. $100 at Oreillys. I would recommend the Deka AGM sold at Sams club. Group 31 for $179.
