I have a 2000 Bayliner Capri 1750 that is having starting issues after being ran and once you turn it off it will not re-start. It turns over but won't crank up. The last time this happened it drained the battery due to trying to crank it so I had to have the boat towed in. I charged the battery and it fired right up. Could the battery be the cause of this issue? The alternator is working because when it is running it shows over 13 amps on the gauge. Any help with this issue would be greatly appreciated.
