I think I located the culprit after laying on my stomach for 1/2 a day unhooking about 100 wires, removing 5 batteries with a chain and a come-along, then removing the battery box floor. This boat has a wash-down pump that is built in way back by the livewell. Once I got the floor out of battery box, I could hear it plainly. I hooked it up and cycled the switch which is located on both the dash and transom. Cycling the switch shut the grinding noise off then it won't restart. I'm assuming the motor is fried. Under warranty.
I'm leaving the batteries out except for the cranking battery which all my accessories run off of. I'll leave the floor out of the area that hides the wash-down pump so Excel has easy access to it, and as soon as I'm able to ride, I'll get somebody to take me and the boat to the Union City,TN plant. I won't need it for 3 weeks or so and that should give them plenty of time to replace the pump.
BTW, the Storm Cat 230 is a 23 foot version of Excel's Storm Cat catfish tournament boat. Catfish guys need a wash-down pump so they can spray down the slimy floors and decks. I've found it very nice when somebody decides to dump a container of nightcrawlers. Before they get ground into the floor, whip out the coiled up garden hose and wash it all down.
Thanks for the comments. The wash down pump is by far the largest pump on the boat with heavy wiring. I just couldn't wrap my head around a stuck bilge pump or aerator. Wiring on those is too small to carry 60 amps.
