In ref to your problem of stopping a marine prop shaft from rotating, identify the direction of rotation of your shaft. Then select a dock line of about 5/8" . If you have a large set screw or bolt that you can secure to on the coupling from the engine, secure this line to same, and then find a good substantial item to secure the other end of the line. You might also make a few turns around the shaft before making the final attachment to the boat. I like to make a bunch of clove hitches if no bolt is available- say 10 - 15 hitches around the shaft. I have used this set up to stop the shaft for two reasons- some of the dripless seals will burn up after 20 or so minutes and some marine transmissions will over heat due to lack of oil and no cooling.
