Trying to get on the water tomorrow. Attempted to start my engine (2001 Yamaha F115 4stroke) and got nothing. Turned the key and the guages came on and as soon as I tried to start the engine it all went dead. There were a couple of clicks then nothing. I have checked fuses and everything seems to be ok. The indicator on my battery charger shows the battery is fully charged. I am guessing it is the battery. Any suggestions??? Thanks!!
