Lencos are on my 21SE. No problems yet, but my boat is on a lift. With that said, the spot-welds are showing signs of, well, let's say decay.
I had Lencos on my last boat. Kept in the water full time, I replaced two actuators in three years. They were under warranty and Lenco sent me replacements immediately w/no problem. Also, the spot-welds rusted (decay as previously described) where the plate meets the joint, causing the plate to separate while underway. I thru-bolted the plates to the joint at the spot-welds after the first break and that prevented future failures.....So....I like FishFactory's Bennett idea.
