Loosen all the way the cable nut from the right side of the steering tube remove the control cables and fuel line. either remove the battery cables from the engine or from the battery terminals. remove at multi colored electrical cable from the engine

If you have a lift, the flywheel has three bolt holes in it either 1/4 X 20 or 5/16. Use a steering wheel puller modified to hoist the engine from the transom. IF it is a later Force with Mercury ignition There is a special Mercury tool for lifting and pulling the flywheel off.
