Need to replace seals and O rings in lower unit, am waiting for manual to arrive. Can't wait, does anyone have experience? I've removed two retainers but still can't remove prop shaft. Is prop shaft housing threaded at front end or am I missing something? Pressed fit? Same for drive shaft, my diagram shows a retainer, is it threaded? Also, are used lower unit cases available? Mine is pretty bunged up; someone at some point drilled out the drain plug and it's tough to get a good seal.
