How many CCA do I need on a battery for a boat my size?

I didnt think about the voltmeter on the dash but I could defintily install
one of those without much trouble. I have installed boot meters and
tachometers in cars before, not much difference.

engine?

The deep cycle that is good, bad, or needs charging is 575 CCA.

I guess I'll try to get one of those dual purpose starter/deep cycle
batteries on the way home since id like to have two anyways. I saw one
with
650CCA and one with 750CCA.
