just bought my first boat and am hoping that someone can help me with a battery questions. The main cranking battery is approx. 5 years old--appears to hold a charge well, but when I got to the ramp this weekend for my maiden voyage I came real close to draining the battery when starting the engine cold--after only 5 or 6 attempts to start. After getting it started and warmed up had more problems and held a charge for the rest of the day. <br /><br />Do I need to replace this battery?<br /><br />thank
