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.
