I'm still looking into the cause of the water getting into the boat. At this point I have no idea what happened. I did determine that impellor on the bilge pump fell off the shaft. WTF? I had to remove the gas tank to get to it and when I removed the top portion of the pump the impellor was laying there in the bottom bracket. The pump is a new pump and I know it worked the first 3 days I had it out this year because I saw it pumping out water that was getting in due to a lose hose clamp and engine bolts that were leaking a bit. I sealed up all those and water wasn't getting into the boat. So the pump was working and then for some reason the impellor worked itself off the shaft causing an immediate and complete failure of the pump.

I will be taking the boat out for a test drive tonight to see if any water is leaking in. It took several hours last night to get the motor running. Any electrical connection that has power and gets submerged will corrode in a matter of hours. I still have the gas tank out and will use a small portable tank so that I can have a clear view of the entire transom area to check for leaks.

I didn't hit anything that I know of. I also just finished a complete rebuild of the boat, new transome and stringers. I also added a very strong layer of fiberglass across the entire inside of the hull. That thing is built like a tank now and it would take serious impact to breach the hull. All the thru-hull fittings are brand new this year and are sealed tight with silcone on the inside and outside.

Anyone interested in learning how to do a complete boat rebuild I have a detailed thread about my build over at http://forums.iboats.com/showthread.php?t=461659
