I should have got pics but I'll try to explain this as best I can.
On my leg, on the outside of the upper gearcase, there is a red plastic plug that when removed gives access to a grease nipple that puts grease where the upper gearcase sits on the lower. I think this is the swivel housing?
Anyway, this red plastic plug is severely broken off - basically all that is left of it is the threaded parts so it doesn't really seal anything. It looks to me like the passage on the inside of this plug is where the exhaust/water come down out of the engine and out the leg. So it doesn't really matter if there is a plug there?
