1982 90 Evinrude virbration problem

[90Evinrude]

i have a 82 90hp evinrude i was using it today and the motor had a little virbration to it and i didn't think it was serious .. but ten minutes later after leaving a friends dock at low speed before plaining off the motor started to virbrate very badly and it turned off ..not knowing what it was i tryed to start it once to not cause more damage but to see if it would start... the motor would not turn over it was just spinning and coughing as if it was trying to start but couldn't and the starter sounded as if it was skipping too...... if anyone can help it would be much appreciated

hopefully all you did was shear the woodruff key between the crankshaft and flywheel. this would throw the timing off. if not you may be in for a rebuild, block or lower unit.


PULLING FLYWHEEL

you need a harmonic balancer puller, you need 3 - #8 harden bolts, that fit the 3 holes in your flywheel. standard hardware store bolts will strip out, causing more problems. loosen the flywheel nut, leaving it on so it protects the thread. thread the bolts in 7/16 of an inch. then tighten the puller, adjust so it has a straight pull. now tighten the puller, rap the center bolt with a hammer, then tighten some more. you may have to let it sit over nite, and repeat in the morning. this is a compression fitting, it will eventually POP!!. do not loose the woodruff key that goes in the groove of the flywheel and the crank shaft. then installing the flywheel, it has to be totally clean, no oil, woodruff key in place. then torque the nut to the specifications for your particular motor. if you do not do this, the woodruff key with shear, and you will be repeating these steps.
