"One unit, the Rapid Jack, is very different from the rest. It incorporates a unique ratchet-lifting mechanism that allows adjusting the engine up or down in easy 1/4 inch increments with one wrench. This is one of the nicest manual units on the market! Rapid Jack offers the most convenient-to-use manual jack. Louisiana's Hydro Dynamics focuses all of their efforts on building high-quality manual jack plates and extension plates."
