Lenco marine customer service.
Really pleased with lenco marine in floridas customer service. If you are in the market for trim tabs they really can't be faulted. My switch disassembled itself and although out of warranty, they sent me one FOC despite it being a few hundred quids worth of kit.
Several years ago I bent some lenco tabs in rough weather and they were equally great. They even upgraded the tabs to a heavier duty FOC.
