  • TESTING DEVICE AND METHOD FOR TESTING A DRIVE TRAIN OR COMPONENTS WITHIN A MARINE PROPULSION SYSTEM HAVING AT LEAST ONE DRIVEN SHAFT
    Publication number: 20230080933
    Abstract: A testing device for testing a drive train or components within a marine propulsion system is provided and includes a first disk with a plurality of first disk depressions that faces a second disk with a plurality of second disk depressions. The first disk and the second disk are secured relative to each other so that they define a space, and a seal at outer edges of the disks is in fluid communication with the space. One of the first disk and the second disk is secured to a driven shaft. Upon rotation of the driven shaft, a load is produced due to shearing of fluid between the disks, yet no thrust is produced.
