Viper wrote:Source of the post For the benefit of those with the same model, are you able to post some pics of the bad areas on the tanks so they're aware of potential issues they may face in the future. Also curious, what does the tank normally sit on, just a platform? If so, I'd consider something that would allow the bottom to breath/dry out.


Here's what the bottom of mine looked like when I pulled it out. I went a different route to pull my tank though.

I'm guessing you pulled your engines? When I had talked with carver they said that the engines would need to get pulled along with the Genset and possibly cut the bulkhead. I decided to avoid that route. Lol. There is no mistaken where your leaks was :-O

Both motors were toast when I bought the boat so they were pulled anyways. When the starboard tanks was replaced in 07 they cut on the stringer to get the tank out. When I did the port side this year I refused to cut on the hull so I got creative with a sawz-all on the tank and had the tank built slightly differently. You can see what I did in my build thread in the project center.

I confirmed my leak by pressure testing the tank in hull. After I pulled the tank you could see a couple pin holes but I picked at them to the size you see in my picture.


Off topic but since I have your attention, any way you can take a look inside your engine room and tell me where the water lines for your prop shaft seals hook up? It was 5 months ago since I took mine apart and I'm having a hard time figuring it out . Thanks

Small update..... No more leaks! Although we could never find the actual hole in the tank, having the new bottom resolved the issue.
