1998 Chris craft 210 open bow V/P 5.7. Turn key nothing. Gauges work but nothing happens when I turn the key to start. I checked the batteries and voltage was good. Check the voltage going to solenoid and was fine. Any other suggestions? Kill switch on, shifter in neutral, even moved it forward and backward a few times to make sure. Put screw driver across two large post on solenoid and got sparks. I'm out of suggestions. A boat guy said it might be the battery breaker but I've looked every where and don't see one on my boat. Please help!
