I have a 2007 225 Optimax Pro XS. I was previously running a 250 SHO and never had issues running a 3 battery system with the stealth ac/dc charging. I have stealth on this boat as well with 3 group 31 deep cycles with 845CCA. I have been told that I will need to run a dedicated cranking battery with this motor. I trust the friend that told me this but wondered if anyone has actually ran a 3 battery system with 36V TM successfully.
