T-H Marine Atlas Heavy Duty Hydraulic Jack Plate

T-H Marine Atlas Heavy Duty Hydraulic Jack Plates

T-H Marine’s Atlas Heavy Duty Hydraulic Jack Plates are built for big outboards and demanding conditions. Designed for higher-horsepower V6 and V8 engines, the Heavy Duty Atlas gives you fast, precise engine height control to help your boat launch harder, run cleaner, and handle better in everything from rough open water to shallow flats.

With the same self-contained hydraulic design that made the standard Atlas the #1 selling hydraulic jack plate, the Heavy Duty series adds increased strength and capacity for heavier modern outboards. It’s a go-to choice for serious anglers, performance boaters, and anyone running a large engine that needs reliable setback and lift.

Key Benefits

• Stronger hole shot and lift – Adjust engine height to get on plane faster, carry heavy tournament loads, and keep the bow riding where you want it.
• Better top-end performance – Fine-tune engine height at speed to reduce drag, dial in RPMs, and help maximize speed and fuel efficiency.
• Improved control in rough water – Drop the engine for extra bite in chop or raise it for cleaner water to the prop, helping the boat track straighter and land softer.
• Enhanced shallow-water capability – Raise the engine for running skinny water, idling through hazards, or loading and unloading at shallow ramps.
• Push-button adjustment from the helm – Hydraulic lift gives you quick, on-the-fly changes using the included dash-mounted rocker switch.

Heavy Duty Construction & Hydraulic System

Atlas Heavy Duty Jack Plates use a rugged one-piece design with the proven rod-and-slot lifting system and engineered polymer lift rods for smooth, reliable movement under high loads. The heavy duty frame and components are engineered specifically for larger, heavier outboards where extra capacity and stiffness matter.

A self-contained hydraulic actuator is built directly into the plate, so there are no separate pumps or reservoirs to mount inside the boat. That means a cleaner installation, fewer potential leak points, and fast travel from bottom to top in just a few seconds. The actuator itself is made in the U.S.A. by a leading name in marine hydraulic design.

Compatible Boats & Applications

Atlas Heavy Duty Hydraulic Jack Plates are a strong match for:

• Offshore and nearshore center consoles
• Big bay and inshore fishing boats
• High-performance bass and multi-species rigs
• Any V6/V8-powered hull that needs extra setback and lift for a heavier outboard

They provide ample vertical adjustment for performance tuning and shallow-water running, and are available in multiple setback options to better match different hull designs and balance requirements. For exact horsepower ratings, maximum engine weight, and setback dimensions, refer to the Specification tab on this page.

What’s Included

Each Atlas Heavy Duty Hydraulic Jack Plate package typically includes:

• Atlas Heavy Duty Hydraulic Jack Plate assembly
• Hydraulic actuator integrated into the plate
• Relay harness
• Dash-mounted rocker switch
• Installation instructions and warranty information

Note: Transom and engine mounting bolts are usually not included. Use marine-grade stainless steel hardware sized for your specific transom thickness and engine mounting requirements.

Installation Notes

Atlas Heavy Duty jack plates are designed for straightforward installation on most outboard transoms. The self-contained hydraulic unit eliminates the need to mount separate pumps or reservoirs, and the included harness and switch simplify wiring.

Because installation requires lifting and supporting a large outboard, aligning the plate and engine on the transom, and properly torquing all mounting hardware, many boaters choose to have the system installed by a qualified marine technician. Always review the installation manual, verify the recommended setback for your hull, and confirm engine/boat compatibility before purchase.

Atlas Heavy Duty Jack Plate FAQs

What is the difference between the Atlas Heavy Duty jack plate and the standard Atlas?

The Atlas Heavy Duty Hydraulic Jack Plate is built with a reinforced frame and components to handle heavier, higher-horsepower outboards than the standard Atlas. While the standard Atlas is commonly used with engines up to 300 HP, the Heavy Duty series is rated for larger V6 and V8 outboards up to approximately 450 HP and 810 lbs of engine weight, depending on the specific model. It is recommended when your engine’s weight and horsepower are at the upper end of Atlas ratings or when you run in especially demanding conditions.

What size engines is the Atlas Heavy Duty Hydraulic Jack Plate designed for?

Atlas Heavy Duty jack plates are designed for large V6 and V8 outboards and are rated for engines up to approximately 450 HP and 810 lbs of engine weight, depending on the setback model. For the exact rating of your specific jack plate, refer to the specifications table on this page and compare it with your outboard manufacturer’s recommendations. Always make sure the jack plate’s rating meets or exceeds your engine’s weight and horsepower.

How do I choose the right setback for my boat?

Setback is the distance the engine is moved rearward from the transom. Smaller setbacks are often used on lighter, faster hulls, while larger setbacks can help heavier boats or rigs that benefit from extra lift and cleaner water flow to the prop. The best choice depends on your hull design, engine weight, running attitude, and how the boat is loaded. If you are unsure, check your boat manufacturer’s recommendations or consult a knowledgeable dealer or technician with your boat and engine details.

Is the Atlas Heavy Duty Hydraulic Jack Plate suitable for saltwater use?

Yes. Atlas Heavy Duty jack plates are built from high-quality aluminum with marine-grade components and can be used in both freshwater and saltwater. As with any equipment used in saltwater, rinsing with fresh water after use and performing regular inspection and maintenance will help maximize service life and keep the hydraulic system operating smoothly.

Can I install an Atlas Heavy Duty jack plate myself?

Many experienced DIY boaters and riggers install Atlas jack plates on their own. However, installation requires safely lifting and supporting a large outboard, aligning the plate and engine on the transom, drilling or re-using mounting holes, and properly torquing all hardware, as well as completing the electrical hook-up. If you are not comfortable with this level of work, a qualified marine technician should handle the installation. Always follow the installation manual and safety guidelines.
