See full version: How to Raise & Salvage a Sunken Boat
Insert the dewatering pumps' pickup hoses into the wreck. Ensure that the discharge hoses are led in a safe direction and start the pumps. The pumps should overcome any water coming into the wreck over the gunwales or around the fother and pump the boat free of water. The wreck should now be floating.
Raising and salvaging a sunken boat is an involved and moderately dangerous process. Weather conditions, sea state, water and air temperatures and predatory or dangerous animals can make the procedure even more difficult. The cause of the flooding must be temporarily repaired to allow the boat to be raised and pumped out, meaning someone has to do repairs with the boat still flooded and possibly still resting on the bottom. Having a certified scuba diver with diving gear that is in good working order is an absolute must-have to keep the project as safe as possible. This project will need a team of people to safely and effectively raise the boat.
Dive down to the wreck and fasten lift bags or inner tubes to the rigging, cleats and any other strong points that are available. Fill the lift bags or tubes with compressed air from the compressor to begin raising the wreck from the bottom. more
Make temporary repairs to the source of flooding. Usually a sunken boat will be holed somewhere in its hull. Stretch the tarp across the hole and fasten each corner securely. The tarp--now called a fother--works to seal the hull and prevent new water from entering. The boat should be floating just below the surface at this point.
Position the standby vessel close to and downwind of the wreck. Pass a length of rope from the standby vessel to the wreck and fasten both ends to tether the standby vessel.
Take the wreck under tow with the standby vessel. Tow slowly and carefully to avoid ripping the fother off and resinking the wreck. Tow the wreck to a boat hoist, ramp or dry dock and secure the wreck on land before attempting to repair the hull. more

The Boat Lift Helper is made of the same tough material that the military uses to raise sunken equipment from the ocean floor. The Heavy-duty air-lift-bags will raise your boat lift up off the lake bottom for simple positioning right from your dock. No need to muscle your boat lift through muddy, sandy, rocky, or weedy lake bottoms.
Oh yeah, I got your redneck solution. We used this method repeatedly to raise boats in our college SCUBA club. Works really well. We bought a literal boatload of inner tubes (the cheap used and leaking variety was fine, we patched them ourselves.) more
Now its a big mess with a bunch of finger pointing [links]
Be ready right away for a patch the water bed mattreses will chaffe and start leaking but for a onetime deal it is a cheap way to go.
