I had been running it fine for about 2 weeks, it did always seem to turn over slowly, but it would start within 2 seconds. Then the other morning I tried starting it, got the 2 beeps, when I hit start it flashed limp home mode then screen went blank, no click, no crank. Replaced the battery at the dock, same thing. I towed it to the ramp at idle speed, no clamp about 15 minute ride. My daughter was the last one to ride it, so I can't say exactly how it ran when it was put up last, but I was out there with her and never noticed anything wrong.

I replaced the solenoid and that got it to turn over but was slow with the ringing sound. I replaced the starter, same thing. I have cleaned the connections. I pulled the pump and it spins freely, I tried turning the driveshaft by hand (no wrench, no plugs) and I could not get it to turn. I did find about a cups worth of water in the muffler, and after doing some more research I think I had too much oil in it (it was right at the top line when cold) So I drained all of that and refilled to in between the marks, and the oil is clean, no water in it.

When starting with the plugs removed there has been no liquids spraying out, I did have clean rags in the holes which would be shot out when cranking. The test without the plugs was done with wot. It did get rained on a few days before it died, I didn't think about it until I got back to the dock after pulling the kids on a tube for about 30 minutes. I opened it up and sucked out maybe 2 gallons of water from the hull, but it did run for a few days after that.

So my next steps were going to be taking the hose off the sc and trying to turn it with a wrench, assuming it turned I was going to start replacing pos/neg wires, but the ringing has got me worried. BTW it is an iS and I have opened it and closed it up so many times recently which is a pain moving the top deck, but sure is nice bouncing over waves, I wanted to get some more knowledgeable suggestions before I get back in there.
