If you are tired of dealing with bad batteries all the time and want an awesome marine battery check these out! http://www.lifelinebatteries.com/marinebatteries.php
Two of them came with my Daytona and they are incredible. Also, I was at Hi Point Marine on lake Texoma at a big Fountain/Skater dealer and these are the only batteries they will use in their boats. They are pretty pricey but they are great!
850 cranking amps in a battery that weights only 32 lbs---should be supreme in a race boat
