Battery size for G@ 300hp

I have twin G@ 300 HP that I need to buy batteries for. What is the spec for the MCA and CCA for these enginines. I am looking to use dual purpose batteries because I have electronics on board. I am looking atthe DEKA 27M which is a dual purpose AGM battery the specs are 580 CCA 900 MCA and 92 ahr.

 

Thanks

The information is in your operator's guide. They are minimum specs, it is always good to be above the minimum for extra safety and capacity.

 

Battery, Minimum
675 CCA (845 MCA) 12 volt 
800 CCA (1000 MCA) 12 volt below 32°F (0°C)

 

Your DEKA is not large enough.
