So I need a new battery and the one I have now is a 24MSX and it says 800CA at 32 degrees F and 1000CA at 0 degrees F. My motor is a 07 yami 50hp 4 stroke. My question is do I need that much CA. I seen a 24MS 625CA at Walmart. Can I get that one or do I need to spend more coin. The current battery has lasted about 4.5 years

Did you consult the owner's manual?

Google found a Yamaha F50 Owner's Manual that says 380 CCA and 502 MCA. Of course use this at your own risk and look up your specific motor.

Thanks. I'm wondering why the present battery had such a high CA
