Lectrotab trim tab standard 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 standard 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 either a standard or low profile transom mounting bracket. Actuators come in 12 and 24 VDC with 8 second recommended stroke time or 4 second stroke time. FEATURES Actuator covered by a Lifetime Warranty Upper ram seal patented location cannot be damaged due to fouled ram or barnacle growth Utilizes patented internal pressure equalization system Upgrades to most popular hydraulic and electromechanical systems Internal brake system prevents unwanted tab movement when under way or backing down Quiet operation All actuators fully load tested to push 1000 lbs of force Non-metallic external structure which cannot corrode and will not deteriorate in the sun or under water
