    battery on 2004 200hp ox66

    Iam using a optima d34m deep cycle for starting battery. It has 750 cca. 120 minutes of reserve. Yamaha owners manuel says 512 cca and 182 minutes of reserve seems like they are asking for a lot of minutes of reserve ? Enrico

    Re: battery on 2004 200hp ox66 (21XDC)

    Mike, I put this battery in because of weight only weights 40 lbs. and went with deep cycle to run electronics charge cell phone. Optima says this is okay to do. My concern is minutes of reserve if the motor charges the battery when running what is the problem ? Enrico
