T-H Marine Atlas Hydraulic Jack Plate, 4 Inch Setback, Rated up to 300 HP

The T-H Marine Atlas Hydraulic Jack Plate (AHJ-4V) is a 4 inch setback hydraulic jack plate built for outboards up to 300 hp or up to 625 pounds dry weight. It uses a self-contained hydraulic pump system, so there is no separate reservoir or hydraulic lines to install, and it can lift the engine from bottom to top in less than 8 seconds. The lifting action relies on a rod and slot design using hi-tech engineered polymer rods that are 6 times more abrasion resistant than steel rods and are made from a self-lubricating material, so no regular grease maintenance is required. The pump itself uses an easy two-pin removal system for quick field maintenance, and the hydraulic actuator is made in the U.S.A.

The transom-side mounting plate measures 16-3/8 inches wide by 12-1/2 inches tall, with a stroke length of 5 inches and height adjustment of up to 7 inches. The plate is predrilled for Power-Pole and Minn-Kota Talon shallow-water anchor bracket mounting, so those accessories can be added without additional drilling. Each unit ships with a relay harness and rocker switch for engine control; mounting bolts are not included. Because setback and height affect handling, contact your boat manufacturer or a local dealer for the correct setback recommendation before installing.
