About the KONRAD STERNLEGS

Konrad Marine is a leading manufacturer of stern drive propulsion systems for global marine applications.
Used under the toughest, most demanding circumstances, Konrad stern drives have been pushed and proven in applications ranging from commercial fishing vessels to military pursuit craft to high performance boats. Konrad stern drives feature thick-walled castings, oversized bearings, precision machined super alloy gears, and Konrad’s exclusive no maintenance U-joint.
The brawny components are cooled by a continuous flow of oil that is circulated throughout the drive, resulting in cooler operational temperatures, added durability, and smoother operation.
Konrad sterndrives feature: oversized bearings, thicker castings, hardened steel shafts, largest u-joints in the industry, continuous oil circulation for cool operation, one piece propeller shaft, precision machined super alloy gears, no corrosive exhaust through drive, no failure-prone cone clutch.

KONRAD 540 PRS
Konrad Marine is a leading manufacturer of stern drive propulsion systems for global marine applications. The Konrad PRS (Performance Replacement System) is a direct bolt-on for obsolete TRS* drives. The old TRS drives and transom assemblies are simply pulled off and the new PRS drives are slid right on over the same bolts.
The engines do not have to be removed. Anyone with a little mechanical know-how can install the PRS in less than a day.
*TRS is a trademark of Mercury Marine, a Brunswick Corporation. Original equipment manufacturer’s names are used for identification purposes only. We are in no way implying that any of our parts are the original equipment manufacturer’s product. More

KONRAD 560 Twin Prop
Konrad Marine is a leading manufacturer of stern drive propulsion systems for global marine applications. The The 560 twin prop stern drive package was designed to handle gasoline or diesel engine torque and was engineered to gain efficiency by sharing the torque load with dual propeller technology.
Counter rotating propellers reduce propeller roll, greatly increasing low speed manoeuvrability for superb docking and substantially improving handling in reverse. The 560 reduces propeller slip, increasing fuel economy and top speed. With its state of the art engineering and highest quality components, the 560 is capable of exceeding commercial market demands.
The Konrad 560 Twin Prop drive features two, one piece stainless steel propeller shafts, fitted with line protection seals. The specially designed stainless steel propellers vary in pitch up to a 16“ maximum diameter.
The major components are manufactured in-house at Konrad, including the gear sets of high grade aircraft quality steel, heavy duty drive shafts and high quality, heat treated aluminium castings. To ensure customer satisfaction, Konrad tests all their stern drives for heat, noise and vibration prior to leaving their plant.
Konrad’s 560 Twin Prop counter rotating drive is based on the military proven 520 with a heavy duty transom assembly. The 560 twin prop offers boat enthusiasts a complete propulsion system for the rigors of recreational and commercial duty on single engine vessels weighing up to 11,000 lbs. More
