    Default Boat Won't Start

    Hey Guys,

    I am hoping this is something silly I am overlooking. I changed out the spark plugs about 2 weeks ago and verified the boat ran after, and it did. Fast forward to present day and I did the full winterization process last night draining all the water. I went to start the motor to run the antifreeze through and it wouldn't start. It wouldn't even turn over. The fuel pump goes when I turn the key and when I try and start it there is ONE single click that is coming from the end of what seems like a relay( at the end of a wiring harness) and thats it. Not sure how that would happen all of the sudden. HELP

    Batteries charged fully? Check kill switch. Make sure shifter isn't bumped out of neutral.

    If you have a battery switch, make sure thatís on too.

    All of those things are checked off and still no luck. Being winterization time too, no place has any availability until December.

    Looks like a starter relay, sometimes they include a fuel pump relay if the boat has EFI

    Looks very similar to the starter relay on my old truck.

    I replaced the relay and the new one still does a SINGLE CLICK when trying to start the boat.
