    Is my carbon seal toast?

    After installing opas block offs and riva rear exaust I thought it would be smart to test for leaks before I sank in the middle of the lake. So I filled the engine compartment with water. I noticed two leaks. One at the rear exaust, tightened it up and that stopped. The other was comming from the intake grate. So I crawled up there and took a picture. Sorry about the driveshaft being fuzzy, the stupid camera won't focus past the intake grate for some reason.

    I don't think this is normal? how hard is it to replace the carbon ring?

    I'm with you on this one lurker i've got the same problem. I haven't put any water in mine yet but the last 2 times i was out in glass conditions i had way too much water in the bilge( about a gallon or two). I'm getting ready to get the driveshaft and pump out of an RXT so i figured this would be a good time to replace the carbon seal.

    That's where mine leaked but when I put water in my hull to find the leak I didn't fill it over the carbon seal. That ring only seals when the water is on the outside of the hull. Water pressure and that boot push the ring against the flange.

    My leak was a weak pump shoe glass job. A few others also had glass issues around the pump shoe.

    You can see the leak here and the weak glass at the top of the pic.

    Mike,

    Just wondering have you fixed those hair line cracks under your hull and if so what method did you use. ie. Did you re apply gel coat or 2pac etc.

    Noticed the same problem with my hull

    the cracks in the shoe were repaired with something. I don't know what. They cut out some fiber and did something. It was warranty work so i didn't pay attention.

    so it is supposed to leak slightly when no pressure is being applied from the outside? That would make sense if the seal is what I'm picturing in my head.

    Yours was leaking where I have circled?

    Mine is not leaking from that area. It is definitely leaking from where the driveshaft goes into the hull.

    I think mines toast. Last 2 times out i had a significant amount of water in the hull. Nothing dangerous just way more than usual and i was riding glassy water.

    I have about 20hrs on mine. After I did that "reverse leak" test I took it out on the lake. Didn't have any water in the hull after the ride (out a couple hours) so I don't know if I should be worried or not. I kept checking during my ride and I didn't have any water. I just hate to take it to the stealer and have it sit out in the elements for 2 months.
