First you need to drain the gear lube from the drive unit.
Remove the lower and upper drain & vent screws and let all the oil drain.
Next, use either a 5/16" or a 3/8" Allen wrench and remove the anode from above the prop.
Now look up where the adone was mounted and you will see a hidden screw. Remove this screw with a 5/16" Allen wrench.
Now use a 5/8" deep socke and remove the two nuts from under the ventilation/cavitaion plate.
Remove the front nut at the very front of the drive with a 5/8" wrench.
Now use a 5/8" open ended wrench and unthread the two side nuts until they reach and touch the housing. One nut at a time unthread each nut and allow the nuts to push on the housing to aid in separating the housings.
Eventually you will get a space between the two housings in which you can GENTLY pry the housings apart.
