I'm looking to replace my current battery and looking for a dual purpose battery. Looking for the best one to get with optimal cranking. I'm limited because of the size of the battery box....what do you guys recommend?

At this point, all I can recommend is "a black one."

Because I am also limited in not knowing the size of your battery box.
What will fit? Group 24, 27, 31 ?

Generally, I would stay away from a walmart battery since they changed them a few years back.

A battery from Farm and Fleet or Napa would be fine, Interstate if you want to spend more money.

I don't have an owners manual for your motor, so don't know minimum required MCA.

Probably could use any one with 450 CCA or 700 MCA.
