T-H Marine offers one of the finest hydraulic jack plate on the market today. This design features an all enclosed hydraulic pump that contains the lift cylinder and fluid in one compact unit. No hydraulic hoses to run, no reservoirs to install, no hoses to drill. Simply mount to the transom and connect to power. The Hydro-Jacker™ is angled at the top to allow most steering cylinder units to clear the plate when fully tilting the engine. Two sets of mounting holes on both the transom and engine side gives additional options to mounting. Treated sides and top retain clean looks even in salt water. Available in two set-back sizes, 6" & 10". Easily handles all V6 outboards, even the heaviest of the new 4-strokes (300hp max).
