4 ft of 1/8" tubing sounds light to me as you now know. Then have 1/4 of the boat weight at the end of 4' is like 5,000ft/lbs on that one tube. This was a recipe for disaster. Is the boat okay? Run it by an engineer next time or even a steel supplier. They have books for this. Raising a boat lift 4' is not the end of the world and can be done just not on 2x1.5 aluminum tube. If you dont have access to a free engineer buddy try your local college set it up as a classroom lab experience and see what they come up with.
