Run a big outboard with the lift and control needed for heavy tournament and offshore-capable rigs with the Atlas Heavy Duty Hydraulic Jack Plate, a high-capacity hydraulic jack plate that helps anglers dial in engine height for better holeshot, shallow-water access, and on-plane performance. Its aluminum construction maintains high strength without adding unnecessary weight, and the rod-and-slot lifting design supports smooth, trouble-free operation under heavy use. This plate adjusts from 5 to 7 in. in height and raises in under 8 seconds, giving bass, walleye, musky, and saltwater anglers fast on-the-water tuning for changing loads and conditions. Transom-side dimensions measure 16 3/8 x 12 1/2 in.; the unit is rated for engines up to 450 hp and includes a relay harness and rocker switch.
