Recently bought a cabin with pier/boat house. Included in the boat house was a 1987 Fisher 15 foot fishing boat, that hadn't been run in about 7 years. I got it out, and was able to use with the trolling motor (was waiting to get it out of the water to check the Evinrude 35 outboard out). A couple of weeks ago, I forgot to lift the boat back out of the water (there is a "come along" lift system in the boat house). The stern of the boat got caught under the door of the boat house, so instead of going with the flow of the waves, the boat filled with water, enough to sink. My wife discovered the boat on it's side, and made the mistake of opening the door, to the boat house, which caused the boat to go "belly up" in the boat house. It is still sitting there, belly up. I've tried various combinations, with the cabling system, to pull the boat up, to no avail. Any suggestions on the easiest way to get this thing right side up? It is sitting in roughly 4-6 feet of water.
