I am working on a 1926 Elto Super G.I have removed the powerhead from the exhaust stack.The propshaft is VERY reluctant to turn.Not frozen,just snug.I’d like to disassemble the gearcase and clean it all out.What needs to be removed besides the 2 retaining screws at the 3 and 9 oclock positions?Does the thrust adjustment screw in the nose of the gearcase need to come out?Right or left hand thread? I’m totally out of my league on this one.Thanks for any help you can provide.Ken Hall
