2014 Moomba Mobius LSV power loss

[Cblevins]

Please help. Yesterday I was out in my boat and we returned to the dock and put the boat on the lift. Everything was working fine. Came back a few hours later and was going back out. The boat would not start or even try to start. The dash lights would not come on. All the lights in the boat and stereo were working fine. I checked both batteries and both showed 12.5 volts. Any suggestions? TIA

Either a main circuit breaker tripped. Look under the helm or by the engine.
The perko switch could be to blame also, check the connection to make sure they are tight and not dirty.
