I have been using the Rapid Jack since 1995; however, I would like to take a minute of your time to talk about a Family I just came to know a little over a year ago... the Hydro Dynamics' team.

Spending only a minimal amount of money getting my injectors cleaned and purchasing a Dual Pyrometer Kit, I got more answers than I got from a good paid lawyer. Chuck Goodman is always near the phone when you need him. Chuck has given me the knowledge I need to advance to new levels in setting up my boat to perform like no other.

In 1995, I purchased a Bullet Bass Boat rigged with a Rapid Jack; again, in 2000, I purchased a Bullet Bass Boat rigged with the Rapid Jack. As a bass angler and professional boat racer in the Stock Bass Boat Class, my jack plate is put to the test every time I run my boat. I place the Hydro Dynamics' Team and its products in an elite group having been around boats since I was a kid.

For years I have witnessed the use of products manufactured by Hydro Dynamics and Nitrox. If you are looking for reliability, quality products, and strong customer service, I recommend Hydro Dynamics and Nitrox. Their products work. You got my word of honor.

"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!"

Mel Smith,
President - Smith Marine

When I think about my friend, Chuck Goodman, it seems to me I have known him forever.  I first met Chuck back in the early 80's.  Chuck called me when I was working with my father at Tide Craft Boats.  He wanted to know if we would look at something new he had made, and give him our opinion.  I asked Chuck what had he made; and he told me a jack plate.  I thought to myself, what could be new about a jack plate? 

Well, I will never forget the evening he arrived.  It was storming and the rain had made for a bad day.  Chuck came into the plant and showed us how his device worked.  This was the first "Rapid Jack" by Hydro Dynamics.  Melvin Smith, my father, told him he definitely had a winner.  He said, "Get a patent as soon as possible, you can go as big as you want, son".  He advised Chuck to show at some of the Dealer Trade Shows to help get the word out.  And, the rest is, as they say, history.

Every product or service produced by Hydro Dynamics has been the industries finest.  Chuck has invented/perfected too many items to list for both fishermen and boat racers.  His influence over his employees has inspired them to produce items that are superior and you know you will receive top of the line service. 

Chuck Goodman has become a trusted business associate, as well as a very good friend.  When I call Chuck he always takes time to listen, a rare talent these days.  When it comes to solutions for high performance, his meticulous machine work is the best by any standard.  Almost all high performance applications require tweaking, and Hydro Dynamics' Team offers whatever assistance is needed.

I don't believe he or I will ever outgrow our "need-for-speed", at least, I hope not.  I am very proud to be associated with Chuck Goodman and the Hydro Dynamics' Team, and glad to call all of them friends.

Rapid Jack Magnum 

Introducing the 6" - 8" Rapid Jack Magnum

Hydro Dynamics is pleased to announce the addition of the 6" and 8" Rapid Jack Magnum to our line up. Previously, the Magnum Series was limited to setbacks of 10" to 15". With the onset of heavier, more powerful Engines we felt the need to expand the Product Line. With more torque and horsepower selecting the right setback for your rig can be daunting. We answered this problem with the introduction of both the 6" and the 8" Rapid Jack Magnum to join the line up of the Big Boy Magnum Series.

AAAs with all Rapid Jacks, the 6" and 8" hold true while raising and lowering of engines with ease using the finest materials and craftsmanship of uncompromised quality; effectively, bridging the gap between manual and hydraulic units.

  • Machined by state-of-the art CNC Machines
  • Constructed of 1/2" 6061 T-6 Aircraft Aluminum
  • Twin Cross Members for added Strength and Rigidity
  • 3600 LB Aircraft Quality Cable
  • 3/4" thick bolting bars eliminates the use of a back-up wrench
  • 4-1/4" of travel; adjusts in 1/4" increments in one minute
  • Bolt Kit included
  • Heavy Duty Rated for All V6 Engines
  • Optional powder coating available

STATIC PLATES MAGNUM


HEAVY DUTY STATIC PLATE
Static Plates are stationary units. Many "riggers" know where they wish the engine(s) to be mounted relative to the bottom of the boat in order to achieve optimum performance of their rig. These installations signify a clean, professional installation. Hydro Dynamics' CNC machining capabilities make an aesthetically clean unit with a flare toward design and elegance. This does not, however, come at a cost of strength. Construction is of  "6061 T-6 Aircraft quality aluminum. Inside the unit are two massive 1-1/4" cross members that offer tremendous rigidity. These units are available in 10" and 12" set back. While the standard 10" and 12" models are available, the transition to a customer's specific needs are usually not that difficult. Boats having at or near "0" transom angles can be easily adapted for proper trim angles with variations of this plate. Illustrated to the left is one of Hydro Dynamics' 3-hole units.


A "Super Clean" Application

The photo featured to the left is a perfect example of Hydro Dynamics' commitment to meeting our customer's needs. This rig is definitely a Show Stopper! One of the most popular uses of the Static Plate is the twin engine application. Featured to the left are two custom units where the customer requested a 2-hole pattern in a super cool powder coated finish. Be sure to see Hydro Dynamics' Gauge Bezel assortment which includes the cable and hose rigging bezels that you will need to accomplish this stylish effect.

These units are custom made according to customer's specifications. Available in 10" and 12" of setback. Consists of 2-side plates; 4- Angles; and, unitized, with twin cross members. Illustrated in optional powder coated finish
