Starter battery size for 3200

[craigdouglas]

I am interested in the size of the starter batteries for a 1997 Maxum 3200. I understand the batteries come in 10, 12, or 14 inch length. My boat came with the 10 inch but the battery box 14 inch. I wonder if someone made a change to a smaller battery.

What engines do you have? The CCA requirements of the engine will dictate the size of the battery. From there, you can decide which 'Group Size' fits the space and meets the CCA requirements of the device they are powering (e.g. Group 27; Group 31; 4D; 8D, etc)

Like shrew said. The boat size/model does not matter. It's the engine you are starting, not the boat model.

What is CCA?

[Phillbo]

CCA (Cold Cranking Ampere), is the rating used to define a battery's ability to start an engine in cold temperatures.

I wanted to know the boat started with as far as battery size? I think it was changed to a smaller CCA because the smaller size was cheaper to purchase.

Put in the biggest that will fit Bigger is always better IMHO!
My 1995 2400 with a 5.7 came with group24, I changed to group 27.
Just my 2c.
