Bennett 12" x 12" Hydraulic Trim Tab Kit w/ All-in-One Control - MW
Bennett 1212OBI 12" x 12" Hydraulic Trim Tab Kit w/ All-in-One Control
Bennett's line of hydraulic trim tabs are known for their power, precision, and durability. This hydraulic trim tab kit allows you to get the most from your boat, no matter what the load, speed, or water conditions. Bennett trim tabs get your boat on plane quickly, which gets rid of hull drag and allows your boat to use less fuel. Trim tabs can also be used to correct uneven loads on your boat.
This Trim Tab Kit includes two Bennett Hydraulic Actuators. These actuators are strong, flexible nylon/fiberglass hydraulic cylinders that push the tabs into position. All hydraulic lines and wires are internal, concealed by the upper hinge, so they're not exposed to harsh environments.
Also included is Bennett's All-in-One Indicator Control. This user-friendly helm control is designed to be a stand-alone unit that's easy to install and operate. This control is equipped with convenient "All Up" and "All Down" buttons, and has auto tab retraction so your tabs retract up when the ignition is powered off.
