we went out to the boat with a new battery. while i was filling the tank, my brother connected the battery on the wrong battery terminal.
i did not checked it. my fault.

so i started the boat and the battery goes boom ...

now the boat wont start anymore... still i have power on the boat .. gauges are working..
music is working .. pumps are working!!

what could have happen`? Do you think the starter is blown away?
Please help )) me

What year engine do you have? If it is 2007 or above there is a 100 amp fuse wire that protected the engine. This 10 gauge red wire runs from the starter.

2003/2004
it the excalibur 330hp

In this case the wire goes from the starter to the circet breaker. Verify that you have 12 volts to the circut breaker

You may have fried your engine wiring harness and it is shorting out. I'll post a pic later of my buddy's boat showing his EX330 PCM wiring harness after the batteries were connected backwards. Pull away the plastic sleeving and check the condition of your harness...
