I have a 09 Ranger z21, with a hpdi 250 Yamaha. I have 2 9 inch units, 1 12inch, and 2 12 ft talons. I was told Yamaha motors need a large reserve to start them. I installed a jump switch last week. I have a vita-plate cranking battery. It is only one year old. After a full day on the water, i cant start my motor. What kind of battery should i invest in??? HELP
