A process and a portable apparatus for performance testing of boat motors, especially with outboard drives. A brake disc is rotatably journalled in a hub of a supporting element which carries brake callipers and a lever arm, at the outer end of which a force-measuring instrument is arranged and is tensioned between the lever arm and a resistance in the form of an arm which can be clamped onto the cavitation plate of the drive. During performance testing of a boat motor, the propeller is removed and in its place the brake disc is non-rotatably mounted on the propeller shaft. The force-measuring instrument is connected to a display which gives directly the braked torque. |
