    Default 06 LSV Taking on Water!!!!!

    New to forum and a new 06 Mobius lsv owner (1st time boat owner at that!!!). Had boat since Labor Day weekend. Today was the first time it's been in the water a significant period of time (6+ hrs). Near the end of our day, the bilge was running nonstop. Buddy with me is an experience boater and said that was odd. Popped open center ski locker/ballast compartment and it was full of water! Additionally, carpet in bow was soaked and carpet throughout most of boat under all seats. I was freaked with how much water we were taking on. Immediately took boat back to the launch and called it a day. Trailered boat and inspected hull...spotless. No damage, holes, cracks, etc.. Drain plug tightly in place but bilge ran for 15 minutes straight with a steady stream of water being pumped out. Water was warm, which (after reading other posts) leads me to believe I might have an exhaust shaft hose loose, cracked, or completely off. Anyone out there run into this problem and am I on point with my assumption that I have an exhaust shaft hose issue? I'm no mechanic so any insight would be appreciated.

    If you can hook up a fake-a-lake or line to your water intake I'd suggest running it in the driveway and closely inspect all engine water hoses. Get in there with a flash light or pen light. If you find nothing, then next place to look would be the packing for the driveshaft but you can only do that while you're on the water.

    By running it out of the water though you'll be able to narrow down whether it's the engine or not first.

    Do you have ballast? Check all the bags and fittings.. Sometimes they leak..

    If you still find nothing after checking all the above put the boat in the water, pop the engine hatch/v-drive hatch and check for leaks. My friend's boat had a small hole from an over drilled screw pilot hole on the intake scupper bracket coming up from the bottom of the boat. Unscrew the screws fill the holes with life caulk life seal and reinstall the screws. That fixed the problem. It was amazing how much water came in his boat from such a small hole over the course of a few hours....

    So the only way to check the driveshaft packing is to be back on the water? I'm so mechanically handicapped that if I were to put the boat in the water, I wouldn't know where to start looking. Of course if you see water coming in, it's a no brainer. Where should I pay particular attention to in the engine compartment? My plan was to take it into the mechanic and have them fix the problem and just call it a season and have it winterized. Sounds like that won't happen and I'll have to take it out again.

    So you can leave the boat on the trailer. Just back it into the water and start the boat up. The packing nuts are right where the drive shaft comes into the boat. You will see two nuts. Put the boat in gear and look down at the packing nuts and see how much water is coming in. I hope that makes sense.

    No brainer there. Someone wasn't taking care of the shaft packing and it happens as the packing cord wears and not maintained. Put the boat in the water and check the gland nut but the leak will be much larger when the boat is in motion. If it is the packing, you then need to have the tools to tighten it and hopefully that will correct it. If not, you need to repack it with new cord. Get yourself some non-wax type cord so you don't have to worry about it for another decade.
