I have a rapid jack plate on my bass boat that came with it when I purchased it. I want to start by saying this product kept my boat on the water when the floods hit & we were doing water rescue. We hit something on the water & it tore up my trim pump. Was able to use the rapid jack to pick my motor up and keep me on the water helping people out. Blew the motor the second day. Dropped a cylinder but kept going.Your product helped us get to people.

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. Hydro Dynamics focuses all of their efforts on building high-quality manual jack plates and extension plates.

I've been buying products from Hydro Dynamics for several years now. I use only Rapid Jacks on the Liberator tunnel boats I sell. Never a failure or problem. I have a lot of custom parts and jack plates built by Hydro Dynamics that are my own design. He's always very enthused about doing new stuff. I recommend Hydro Dynamics' products for anyone's performance boating needs. Thanks Hydro Dynamics!
