Fleming Yachts

Fleming Yachts has been obsessed with quality and reliability since the very first hull was designed. So, it’s no surprise that the Aquadrive System has been standard equipment in the Fleming 55, 65 and 78 since the beginning. The reliable, smooth, and quiet operation has left both Fleming and their customers satisfied.


After installing Aquadrive , the U.S. Navy high speed patrol boats enjoyed improved performance with CV joints on boats originally built with universal joints. Personal reported a smoother ride with less vibration and reduced noise. The CV axles were then installed on 25 new 34-ft U.S. Navy water jet boats designed and built by SeaArk Marine.

Schooner Denis Sullivan

The S/V Denis sullivan is a 137′ three masted replica schooner built in 2000 to be used to educate people about the great lakes and sailing as part of Discpovery World in Wisconsin. It is now owned by World Ocean School and continuing its mission to educate. The 135′ vessel has two diesel engines and was originally equiped with an Aquadrive CV30 20480 system. After tens of thousands of hours, the thrust bearings were updated to Moduline B30 units.

Shoreline Sightseeing

Shoreline Sightseeing, then “Shoreline Marine Company” has been in operation since 1939 offering tours of the Chicago Illinois area. In their many years of operation they have operated many vessels and their current fleet of 11 touring vessels and 7 water taxis are primarily equipped with Aquadrive systems. These range from the CVB30.20, HDL42.680 and HDL48.690. They enjoy the smooth quiet operation as well as the added benefits of lower maintenance costs and less down time. Visit


The EELEX 8000 is a high performace 26′ 100% electric powered boat pleasure boat. This boat has a single 170KW eletric motor that allows it to reach speeds of 30+ Knots and has a

Carolina 25

Engines with remote mounted stern drives.

In the Carolina Classic 25, the engine is installed in the center of the vessel, giving it superior balance, and handling due to improved, low center of gravity. The engine is installed 88 inches from the stern drive and the old steel tube CV driveshaft experienced “critical whirling” at specific RPM’s due to it’s excessive length. This vibration and shudder can do harm and generates noise.  This shaft was replaced this with a new one made of a lighter composite material eliminated the problem.

Wahl Construction

Live-aboard, oil field supply vessel in Alaska rivers

The Dana Cruz is a 91′ River & Ocean going, live-aboard tug.  Powered by three 600 HP CAT C18 diesel engines, this tug is operated for long durations without stopping.  During construction it was outfitted with an HDL60.780 Aquadrive CV joint and thrust bearing systems protect the transmission and engine from damaging shock loads and shaft misalignment. They dramatically reduce noise and vibration, reducing crew stress and fatigue.
