T-H Marine ATLAS 6" Setback Hydraulic Jack Plate – Heavy Duty – AHJ-6VHD-DP

The T-H Marine ATLAS 6" Setback Hydraulic Jack Plate (AHJ-6VHD-DP) is engineered for serious performance boaters who demand strength, precision, and reliability. Built for heavy-duty outboard applications, this premium hydraulic jack plate delivers smooth, push-button engine height adjustment to maximize speed, efficiency, and shallow-water capability.

Featuring a 6-inch setback, the ATLAS jack plate improves propeller efficiency, hole shot, and overall boat handling. Its high-strength aluminum construction with a durable, corrosion-resistant finish makes it ideal for freshwater and saltwater use. Designed to handle high-horsepower outboards, the AHJ-6VHD-DP offers rock-solid stability even under extreme loads and high speeds.

The integrated hydraulic system provides fast, precise vertical travel, allowing on-the-fly adjustments to optimize performance in changing water and load conditions. Compatible with most major outboard brands, this ATLAS Heavy Duty jack plate is a favorite among bass boat, bay boat, and performance boat owners.

What’s in the Box

The AHJ-6VHD-DP comes as a complete kit for standard installation, though some specific mounting hardware may be required depending on your boat.

  • ATLAS Heavy Duty Jack Plate: The main 6" setback hydraulic assembly.

  • Wiring Harness: A complete relay harness for electrical connection.

  • Rocker Switch: A standard dash-mounted switch for controlling the lift.

  • Safety Cable: A heavy-duty cable designed to protect the cockpit in the event of engine failure.

  • Technical Documentation: Installation instructions and warranty information.

Note: Mounting bolts to attach the plate to the transom or the engine to the plate are not included and must be purchased separately.


Key Specifications & Features

  • Engine Rating: Designed for modern, high-power engines up to 400 HP (some newer ratings list up to 450 HP).

  • Speed: Features a fast hydraulic actuator that can lift the engine from bottom to top in less than 8 seconds.

  • Maintenance-Free: Uses high-tech engineered polymer rods that are self-lubricating, meaning no regular grease lubrication is required.

  • Self-Contained: The hydraulic pump and actuator are built into the plate, making it significantly easier to install than split systems.

  • Predrilled: Factory-ready for mounting Power-Pole or Minn Kota Talon shallow water anchor brackets.

Installation Advice

Because the engine rigging is extended by 6 inches, you should verify that your battery cables, steering hoses, and throttle cables have enough slack. In some cases, you may need to replace these with longer versions to ensure full range of motion.

The T-H Marine ATLAS 6" Setback Heavy Duty Hydraulic Jack Plate is the ultimate upgrade for boaters looking to unlock peak outboard performance with confidence and control.
