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.
