A mechanical seal device for a drive shaft extending through an opening in the hull of a watercraft, said device being adapted to prevent leakage of water into said hull through said opening, which device comprises a stationary part (1) coupable to the hull and a rotary part (2), rotatably coupled to the stationary part (1) and integrally connected to the drive shaft. The stationary part (1) and the rotary part (2) are provided with a stationary annular sliding element (10) and a rotary annular sliding element (20) respectively, which annular sliding elements (10, 20) are each provided with a flat contact face (100, 200) the two contact faces (100, 200) being in coplanar relationship and in contact with each other. Both the stationary part (1) and the rotary part (2) are provided with biasing means for urging the stationary annular sliding element (10) and the rotary annular sliding element (20) respectively towards each other. |
