    98 xpl sheared flywheel key

    I had a post a week ago about a 98 xpl that I thought had the wrong flywheel. bought a used one from reg. Got to putting it on and behold. the key was sheared. thanks for the help. do not know why. I did have one huge back fire while trying to start the boat. could that have done it or was it put together wrong?

    My guess would be the backfire. It is pretty hard to put it together wrong.

    I would think you put it together wrong-- I have seen it before -- more than once. I have NEVER seen a sheared 951 key when the flywheel was installed correctly.

    If the key has been sheared off the flywheel wasnt installed correctly. the key doesn't hold it in position on the crank at all . The key only lines up the flywheel onto the crank only when installing and the front bolt does all the work . I usually drop the flwheel into a tub of boiling water for 10 minutes and then install and tighten bolt then the flywheel cools and shrinks and locks down over the crank.

    could just use a torque wrench and Blue Locktite..

    I did not do the install. I actually paid someone. The keyway is very small. the flywheel and mag are heavy. a large inertial mass. I am happy to find the problem.
