'™ TRIM TAB SYSTEM CONCEPT & DESIGN The Lectrotab concept is to offer a non-hydraulic trim tab actuator which cannot corrode, requires no maintenance, is permanently sealed, will continue to operate with a fouled ram, has strong deploying as well as retracting power and requires no installation space inside the boat. The Lectrotab design, as shown at the right, addresses all of the above original concept criteria and much more. With no components to install inside the boat, original installation time is greatly reduced. The positive "stop and lock"drive mechanism allows precise positioning and absolute lock against tab deflection when backing down or if the tab is used as a boarding step. And oil can't leak-there is none. Check the design call outs for additional design features. wire exit position match the screw pattern and hydraulic connection of the most popular hydraulic type. An additional screw-hole pattern is also design, have no welds, are hinge rotating area to become fouled. Hinge pin is of 316 stainless steel.
