T-H Marine ATLAS Micro Jacker AHJM-4 Hydraulic Jack Plate for Small Outboards up to 115 HP / 425 lbs
T-H Marine ATLAS Micro Jacker AHJM-4 Hydraulic Jack Plate for Small Outboards up to 115 HP / 425 lbs
The T-H Marine ATLAS Micro Jacker (AHJM-4) is a self-contained hydraulic jack plate built for small outboards, engineered to be the smallest and lightest hydraulic jack plate in its class. It is rated for outboards up to 425 pounds dry weight and 115 horsepower, making it a fit for shallow-water rigs such as Gheenoes, river runners, jon boats, and skiffs where getting up and out of trouble fast matters. The unit uses self-contained hydraulics, so there is no external reservoir or hydraulic lines to run, and it lifts an outboard from bottom to top in just 8 seconds.
The Micro Jacker has a compact 4 inch setback and a small footprint of 14-5/8 inches wide by 11-1/2 inches high, keeping the transom profile tight on smaller boats. With the unit installed, boaters get roughly 8.5 inches of total working height: 1.5 inches of adjustment at the transom, 1 inch on the motor side, 1 inch of adjustment with the motor, and a full 5 inches of hydraulic lift from the jack plate itself. It is constructed from aluminum with a silver finish for durability in a marine environment. For outboards that mount with clamp-on brackets instead of the standard BIA bolt hole pattern, the optional AHJM-CMA Clamp-On Motor Adapter allows those engines to be fitted to the ATLAS Micro Jacker.

Fitment
Fits small outboards up to 425 pounds dry weight and 115 horsepower. Not compatible with Honda's 115 HP outboard, which exceeds the 425 pound dry weight limit. Outboards with clamp-on motor brackets require the optional AHJM-CMA Clamp-On Motor Adapter, since they do not mount to the standard BIA engine hole pattern.

Frequently Asked Questions
What is the maximum outboard weight and horsepower for the AHJM-4? The T-H Marine ATLAS Micro Jacker AHJM-4 is rated for outboards up to 425 pounds dry weight and 115 horsepower.
Will the AHJM-4 work with a Honda 115 HP outboard? No. Honda's 115 HP outboard exceeds the 425 pound dry weight limit of the ATLAS Micro Jacker AHJM-4, so it cannot be used with that specific engine even though it falls within the plate's 115 HP rating.
How much setback does the Micro Jacker provide? The AHJM-4 has a fixed 4 inch setback, which keeps its footprint small at 14-5/8 inches wide by 11-1/2 inches high.
How fast does the jack plate lift the outboard? 8 seconds is all it takes for the ATLAS Micro Jacker to lift an outboard from bottom to top.
How much height adjustment does the AHJM-4 offer? About 8.5 inches of total working height: 1.5 inches of adjustment at the transom, 1 inch on the motor side, 1 inch of adjustment with the motor, and 5 inches of hydraulic lift from the Micro Jacker itself.
What is the AHJM-4 made of? The ATLAS Micro Jacker is built from aluminum with a silver finish.
Can I mount an outboard with clamp-on brackets to this jack plate? Yes. Outboards with clamp-on brackets do not fit the standard BIA engine hole pattern, so the optional AHJM-CMA Clamp-On Motor Adapter is used to mount them to the ATLAS Micro Jacker.
Does the Micro Jacker need an external hydraulic reservoir or lines? No. The AHJM-4 uses self-contained hydraulics, so there is no separate reservoir or hydraulic line installation required.
What is included with the AHJM-4? The AHJM-4 ships as the ATLAS Micro Jacker unit itself; the AHJM-CMA Clamp-On Motor Adapter and the 7014G replacement wiring harness are sold separately.
What boats is the Micro Jacker best suited for? Shallow-water boats such as Gheenoes, river runners, jon boats, and skiffs are the primary use case for the compact ATLAS Micro Jacker.
What is the warranty on the AHJM-4? The T-H Marine ATLAS Micro Jacker AHJM-4 carries a 90 day manufacturer warranty.
