BENNETT MARINE XPT Premier Hydraulic Trim Tab Systems

IMPORTANT INFORMATION

One of the unique features of the Bennett Trim Tab system is the use of concealed, through the transom hydraulic fittings. However, there are cases of complete inaccessibility inside the transo1n, makiI1g the use of the standard Bennett actuator difficult. For such instances, the external line upper hinge is available. This special upper hinge solves the inaccessibility problem by allowing the hydraulic line to e11ter the transom where there is no obstruction. The hydraulic tubing connects directly to the back side of the upper hinge of the actuator and is fed through the transom above the waterline. A “clamshell” cover is included with each upper hinge to cover the tubing where it enters the hole in the transom.
