Easy in theory, but I had a nightmare swapping it !

Took it off ok, except that I need to get longer hex bits. Then realised it wasn't coming off without the exhaust out of the way, so needed to buy a proper trolley jack to get the height I needed.

Got the prop off and back on, then the exhaust and only then realised that the exhaust clamp wouldn't make it past the prop, so off with the exhaust again.
Rounded off one of the allen bolts when removing the prop second time, so had to drill and extract it , get a new set of bolts and do it properly all over again !

Oh well, it's on now, and I've got some shiny new tools as a result

Another one of those simple jobs that turned into a bit of a marathon !
