Bennett actuators are strong but flexible nylon/fiberglass hydraulic cylinders. The piston-like arms push tabs into position. Fluid flows through a concealed hole in the upper hinge at the top of the actuator — thus eliminating external hoses subject to damage.
For external line actuator for use where space inside the transom is inaccessible. Unlike the standard actuator, the external line hydraulics enter the transom by means of external tubing above the waterline.
