I have heard that it works well, i lean towards fixing the seals to run with proper lube, but i been told for the ones that just wont seal, that grease is the way too go.....i think i would leave some air space for expansion, as minimal as it would be.......

so on the advise of guys from Fiberglassics ( which I can not open for few days now) I have ordered John Deere Corn Head grease......and I think I will just fill the whole gearbox with it to insure gear lubrication......

Yes, I have that out.....the pin I was showing is a propeller drive clutch shear.....amazing what one can learn from reading about and understanding the components......your idea will work then !!

I think there should be a single coil spring or wire that retains the plate. With it removed the plate should slide off the prop shaft. You could try turning the lower unit so the propshaft is vertical. With the gearcase up, tap the prop shaft on a piece of wood. The plate should fall off with gravity and impact.

plate started to move: back and forth - due to limitation from the pin....not sure what to do with the pin - I was able to pound it in a little, but have a feeling that this is not a good idea, it's there probably not to let the plate spin......
