i've almost finished working on cleaning the box and its parts. before i start putting in the new replacements, does anyone know if it is normal for the gearbox oil to come out of the back of the gearbox? (where the splined shaft is)

made a mess of my floor when i tilted it a bit...

Totally normal, especially the bit about not expecting it and having to clean it up

and my boots ! Living and Learning!

If you fit the prop it shouldn't leak . Possible to fit temporary bungs whilst removing/refitting / moving etc

I cut off the rubber part of the vibration damper and use that until read to to slide the prop on, still loose a bit but not the gallons i used to.
