05 XStar leaking at prop strut - HELP!

[btmswhite]

Noob here, I just bought an 05 X Star and the bilge kept turning on while out last weekend. After reading through the posts on this site I decided to fill up the hull and check it out. Once it was full I noticed water coming out from the shaft.

Has anyone had this issue? Need to know what to do to stop the leaking.

thanks~

I've got to imagine that's the packing. There should be plenty of posts here on how to replace it.

that's a dripless shaft seal in that boat
check to see if the clamp is tight
Also see if water is coming in from exhaust flapper flange or rudder port
depending on the volume of water it could be ballast tanks

snork, you know your boats but I thought mc didn't go to oj dripless shaft seal till 06. I could be wrong.

I could be wrong, thought it was '04 for the XStar

this one is definitely dripping! so much that the bilge turns on every hour or so. Need to get this tightened up.

Now that you found it by the fill the bilge test, put the boat in the water and examine the same area inside the boat. Given it's a v-drive, flashlight and inspection mirror will come in handy. Find out if it is coming through the packing/dripless or somewhere else.

Have a look see at this thread of an example of what somewhere else could be - http://www.mastercraft.com/teamtalk/...ad.php?t=52945. This is a direct drive but same thing. Although if that were to be your case, the v-drive puts the engine right above the shaft log and will make doing the same repair a bit more difficult. Not sure if new boats have this same design so it is just a thought.

The other reason you need to check to see if water is coming in there from inside the boat is that if you do have a OJ dripless installed, there is a water/cooling line that runs to it. On mine, that water/cooling line runs between the dripless and a fitting on the oil cooler. That dripping you see could be normal as it is just draining from the cooling lines.

Had the same problem on my 05 x45. If you filled the hull up with water on the trailer, then that's the leak. Start with the shaft seal first. It will "leak" from that spot if you run with a fake a lake on the trailer. Than is designed for cooling. This is if it has the newer style dripless seal with the cooling line. Mine was the older style with no cooling line. It should not leak there with boat not running. Check that the line going to the dripless seal is connected and check for holes. Also check that the clamps are tight. If this all checks out, you will need to replace the seal. Not a fun job on my boat with the 8.1. Basically had to stand on my head to get down to it.

Most likely the packing gland. In 2005 the gland was not lubricated by water like the 2006 and newer. It probably has finally failed if it has not yet been upgraded to the new style. I would start there.

Thanks for the advice. The shaft seal was shot and completely burned out. It was close to disintegrating when it was taken out. Dropped a new seal in there and no more leaking.

I pulled my 2012 X14V out today and water was literally pouring from the shaft seal. Seems odd since the bilge never ran even once all day. I guess I need to fill the bilge up with a hose and see if I can recreate the problem, and/or run the engine from the installed flush valve. Other thoughts here are certainly welcome.

[seth25]

The newer drip less shaft seal will have a water supply line to cool the seal. If you are running the boat from a fake a lake or similar devise, yes, water will be coming from the seal.

Seth - So, would it be (potentially) normal for water to run from this seal for 2-3 minutes after going on the trailer?? My 2002 X9 didn't do this, so I was a little freaked out. TIA

Anyone? Thoughts on this? I'm thinking of heading to the dealer tomorrow with a list of items to check out.
