Batteries for 98 Maxum 4100 SCB

[maxumboat]

Hello - does anyone know what the factory specifications for both the engine start batteries and house batteries are? It is a twin Cummins diesel engine boat. I'm having trouble finding out the batteries specified by the factory. Thank you in advance.

CCA for the starting batteries are spec'd by the engine manufacturer. What model Cummins are they?
