Mercruiser 3.0 No Power

[Goskigo]

I have a 2004 Mercruiser 3.0L I/O Pontoon.

I just had my local marina replace the slave solenoid, alternator and belts.

Get in the boat today, blower on. Go to start, turns over once and lost all power. No blower, no bilge, no radio, no ignition.

Is this a fuse problem or did they cross up some wires?

Oh, everything worked prior.

Losing everything check the battery cables. Might have taken them off and was fully reinstalled

There is a 50 amp breaker on the motor, has a red button. If it is pushed in and clicks then it tripped. If it pushes in and no click then it didn't

If all looks good then need a voltmeter and start tracing. That said, I would ask the marina about the issue

Contacted Marina today. They said the issue was a faulty battery cable. Said it was corroded and thus replaced. Started up today with no issues......see what happens tomorrow

I would say it was a corroded cable end which needed to be cleaned. They don't clean, just replace
