I recently acquired a sweet 1989 Supra Mariah. As with lots of boats this age, it had a few problems. One particular problem was that it was taking on a significant amount of water. I'd need to run the bilge pump anytime we stopped the boat to get the excess water out. I tried to find the leak while it was in the water, but I didn't have any luck, so I trailered it, and took it home to flood the hull. This was the result.
