12 V Trim Tab Actuator – 23′ Cable Lectrotab trim tab actuators are precision-engineered to combine quiet operation with a non-hydraulic, maintenance free design.  The unit is corrosion free, ensures very accurate tab positioning, provides maximum lift force, and is totally self-contained for easy installation.  The actuator assembly is packaged in a non-metallic permanently sealed housing. No components need to be installed inside the boat.  Most importantly, unlike hydraulic trim tabs, there is no oil to leak out.  The actuator incorporates a transom mounting bracket. Features:Upper ram seal location cannot be damaged due to fouled ram or barnacle growthUtilizes internal pressure equalization systemUpgrades to most popular hydraulic and electromechanical systemsInternal brake system prevents unwanted tab movement when under way or backing downQuiet operationAll actuators fully load tested to push 1000 lbs of forceNon-metallic external structure which cannot corrode and will not deteriorate in the sun or under waterTechnical Specifications:Actuator DC Voltage – 12 VActuator Stroke Length – 2.25\
