Custom Units

The Ratchet on the Hydro Dynamics exclusive patented Rapid Jack mangnum Transom Jack Plate, lets you move your marine outboard engine from lower positions for family boating to upper positions for maximum speed in minutes.

The patented ratchet mechanism easily and accurately adjusts. Just count the clicks to measure. The 3600 LB test Aircraft Quality Cable raises and lowers your outboard engine to a full 4-1/4" so smoothly and easily that even a child can do it! The "floating harness" cable assembly assures consistent level lifts.

Please Note: Not all Rapid Jack Magnum's will work on all hulls. Some Boats require a custom built unit due to the hull and transom design. You can find these specific makes and models here.
