T-H Marine · Hydraulic Outboard Jack Plates

T-H Marine AHJ-12VHD-DP ATLAS Heavy Duty 12-Inch Jack Plate

Position your outboard with the ATLAS Heavy Duty hydraulic jack plate in a polished silver aluminum finish. AHJ-12VHD-DP provides a 12-inch setback and 5¾ inches of hydraulic travel, with a relay harness and rocker switch supplied for adjustment. Choose this configuration only after confirming that a 12-inch setback is appropriate for your boat.

Features & Benefits

  • Hydraulic vertical adjustment with a listed eight-second rise time.
  • Polished aluminum construction for the silver-finish ATLAS Heavy Duty configuration.
  • Field-replaceable actuator simplifies service access.
  • Heavy-duty safety cable is incorporated into the ATLAS design.
  • Supplied relay harness and rocker switch make the control-package contents clear before installation.
  • Made in the USA, as listed for this product.

Boat & Engine Compatibility

This is an outboard motor mounting accessory, not a vehicle-specific part or a universal approval for every hull. Before purchase, obtain your boat manufacturer's or dealer's setback recommendation and check how the added jack plate affects your particular installation.

  • Confirm the transom and outboard mounting arrangement, available clearance and suitability of the 12-inch setback.
  • Review engine weight as well as horsepower, and follow the lowest applicable boat, engine-installation and jack-plate limits.
  • Current T-H Marine Heavy Duty information lists up to 450 hp. The exact polished-part supplier specification lists 625 lb; verify both limits against the supplied unit's label and instructions before installation.
  • Do not apply specifications from the black-finish ATLAS, ATLAS MAX or Classic series to this part.

The 12-inch setback is not hydraulic lift. The supplier lists 8¼–9¾ inches of total rise separately from the 5¾-inch hydraulic stroke, so review the actual mounting geometry with your installer rather than treating these figures as interchangeable.

Frequently Asked Questions

Q: What is AHJ-12VHD-DP?

A: It is the polished aluminum ATLAS Heavy Duty hydraulic outboard jack plate with a 12-inch setback. Match the complete AHJ-12VHD-DP number when replacing an existing plate; the black-finish model has a different part number.

Q: Is 12 inches the amount of lift?

A: No. Twelve inches is the setback. Hydraulic travel is 5¾ inches; the exact-part listing gives an 8¼–9¾-inch total-rise range. These dimensions describe different aspects of the plate and should not be interchanged.

Q: Will it fit my boat and outboard?

A: A 12-inch setback must be approved for your particular boat. Have your boat manufacturer or marine installer check the transom, engine, steering and control clearances, mounting arrangement and applicable load limits before ordering.

Q: What engine rating should I check?

A: T-H Marine currently lists the Heavy Duty series for engines up to 450 hp. Keystone lists 625 lb for this exact polished part. The installed unit's label, supplied instructions and the boat's limits must all be respected; do not select the plate by horsepower alone.

Q: Are the controls and owner's manual included?

A: Yes. The package listing includes the hydraulic jack plate and owner's manual, while both manufacturer and supplier information identify a supplied relay harness and rocker switch.

Q: Are the mounting bolts included?

A: No. Mounting hardware is not included. Your installer must select the appropriate hardware for the approved transom and engine mounting arrangement; do not assume the controls package contains mounting bolts.

Q: Why does the yellow ruler show less than 5¾ inches?

A: T-H Marine explains that the Heavy Duty ruler is a visual reference showing approximately 4¼ inches. Its taller polymer rods and built-in lift affect that indication; it is not the same measurement as hydraulic actuator travel.

Q: Can the actuator be replaced, and does the plate need routine greasing?

A: The ATLAS design permits actuator replacement in the field, and T-H Marine says regular grease lubrication is not required. Continue the inspections and care specified in the supplied manual; serviceability does not mean the complete installation needs no maintenance.

Choosing the 12-Inch Configuration

This polished Heavy Duty model suits an approved outboard installation needing a 12-inch setback and hydraulic height adjustment. Before ordering, compare the complete part number, setback and finish with your installation plan. Retain your boat and engine details with that plan so the selected plate and separately required hardware can be checked together.

Manufacturer Warranty

T-H Marine's published ATLAS hydraulic jack-plate policy provides three years of coverage for manufacturer defects and a limited lifetime frame warranty for the first retail purchaser, subject to its terms and exclusions. Racing and commercial use, improper installation, normal wear, ancillary equipment and removal or reinstallation expenses are among the exclusions.
