Flywheel Stuck, in the Powerhead what do?

[CHAD FRANKS]

My flywheel is stuck, I read through the forum, took my lower unit off and it's somewhere in the powerhead, put marvel mystery oil in powerhead, sat overnight, took spark plugs out, pull on flywheel with rope, still stuck, it was turning fine before the winter, do i put in more oil and wait longer or is this not cureable

remove the flywhell cover or recoil starter assy. use a 1/2 drive breaker bar and the appropite size socket,preferably a 6 point one on the flywheel nut. try to rock it back and forth. sounds like it may have had a touch of water in it somehow.off hand I cant remember the size of the flywheel nut. but use the marvel oil, its good stuff just tilt the motor full upand let it sit over night. hopefully its not a trashed crank.
