Huckleberry,That video has the side port on the 40HP motor. The 6HP motors came in 3 different arrangements depending on year of manufacture.1:You had to take the powerhead off to get at a pin to disconnect the linkage2:There was the small plate which as in your video is ~midway on the lower 'leg'3:You had to remove the bolts and put the shifter in gear to lower the gearcase enough to expose the linkage in the now opening so you can remove the bolt to remove it fullyI think that particular year as per my link is #3
Huck,I already posted that very same link. We are repeating ourselves here....
