I have a flats boat, with a 2003 4 Stroke Outboard. I want to change out my main battery for a stronger, better quality battery. The main battery runs the engine starter, hydrolic tilt, small Lowrance GPS, nav lights, bilge pump and ac outlet plug (for cell phone charging emergencies only). When selecting a relacement battery, will my choice affect the performance of my engine? In laymans terms...do I need to select a specific battery based on this engine - or will any old crank battery do thie trick... Any suggestions on battery selection? Is Optima really worth the money? Thanks in advance for your time...Michael

Thanks Brett...pulled up the operators manual online (at the Yamaha website) which confirmed your advice. Should have thought to do that before posting. Any experience with Optima batteries? Any other brand which you would suggest?
