Got this problem with my 2008 Lowe Roughneck 1448.
I have had the boat for about 8 months now. Last summer, I noticed it would take on a little bit of water and I thought it might be seeping through the drain tube. The hull is super clean. Over the last couple of months, the leak started to become noticeably worse and I had the feeling it wasn't the drain tube.
I tried filling the boat with water just to diagnose where the leak was coming from. Go figure, it held water perfectly. I had the drain tube replaced recently just in case, and that didn't make a difference at all.
The leak is kind of really bad now while I am running the boat. It takes on about a gallon of water or more for every 20 minutes I run the boat. While at rest, it's not so bad, only takes a tiny bit of water. It's still a bit concerning.
I wonder if there's possibly a crack in the hull weld that's flexing while the boat's running and it's becoming worse.
My boat has a floor. It has foam under there which I've really wanted to get rid of anyway.
Thinking about pulling the floor and seeing what's there.
Appreciate any suggestions on how to diagnose and fix the problem. I think once I find the leak, its just a matter of having someone weld that area again?
