T-H Marine ATLAS 6" Set Back Hydraulic Jack Plate – STD Duty Polished – AHJC-6V-DP

The T-H Marine ATLAS 6" Set Back Hydraulic Jack Plate (AHJC-6V-DP) delivers precision engine height adjustment, improved boat performance, and reliable strength in a sleek polished aluminum finish. Designed for outboard engines up to 300 HP, this standard-duty hydraulic jack plate allows boaters to fine-tune propeller depth on the fly for optimal speed, fuel efficiency, and handling in varying water conditions.

Built from aircraft-grade aluminum and engineered with ATLAS’s proven hydraulic lifting system, this jack plate provides smooth, quiet, and dependable vertical movement. The 6-inch setback improves leverage and hull performance, helping boats achieve faster hole shots, higher top speeds, and improved shallow-water operation. Whether you’re fishing, cruising, or running performance boats, the ATLAS jack plate gives you total control at the push of a button.

Proudly made in the USA, T-H Marine ATLAS jack plates are trusted by tournament anglers, boat builders, and performance enthusiasts for their durability, precision, and clean installation.

Key Performance Features

• Self-Contained Hydraulics: Unlike older jack plates, the ATLAS features an internal actuator, meaning there are no hydraulic pumps or reservoirs to mount inside the boat. This simplifies installation and saves valuable bilge space.

• Fast & Powerful Lift: The heavy-duty actuator can lift the heaviest V6 outboards—including high-torque four-strokes—from bottom to top in under 8 seconds.

• Rodless Holeshot Design: The plate utilizes high-tech self-lubricating polymer rods and bushings that are 4x harder than bronze. This "rodless" design ensures the plate moves smoothly without the need for frequent greasing.

• Polished Finish: The "DP" (Dolphin Polished) finish provides a high-shine aesthetic that complements premium bass boats and performance vessels while offering excellent corrosion resistance.

Why Choose the ATLAS 6" Hydraulic Jack Plate

The T-H Marine ATLAS AHJC-6V-DP offers a perfect balance of strength, precision, and ease of use.

Summary for the User

The ATLAS series is widely considered the industry standard for hydraulic jack plates because of its reliability and speed. The 6-inch setback is the most popular size as it moves the propeller into "cleaner" water for better bite without significantly shifting the boat's center of gravity.

Installation Tip: To maximize the performance of this plate, consider adding a Digital Gauge Kit so you can see your exact plate height from the helm, allowing you to find the "sweet spot" for every water condition.
