What is the best way to lift a 16.5 Alumacraft with a 75hp Yamaha and steering? I need to get it up off the Keel Rollers so I can replace them. I hit some rocks and need to sand the Keel smooth as it is cutting up the rubber on the Keel Rollers to a point that they (4) need to be replaced. Taking it to the lake is not an option at this point. Any help would be appreciated.
