Sterndrive 620

The Konrad Model 620 Stern Drive is considered the "workhorse" of the 600 Series fleet. This drive is engineered with the largest, strongest gears in the commercial, diesel sterndrive industry. Konrad's model 620 is an extremely reliable, robust drive. Combining Konrad's proven single 20 inch (51 cm) propeller technology with stronger shafts and gears, the 620 has set a new standard for stern drive durability.
