Mine isn't like that at all and unfortunately your photo has highlighted another problem, I'd been under the false impression that my cylinder was from a MK4 or even an S but with a single piece cocking arm added.
Looking at your picture and cross referencing the Mercury parts diagrams it would appear that my cylinder is off a MK1 or MK2 as it has one central bolt holding the fore end screw bracket not two a shown in your picture --- bugger.
In view of the above it may not be that simple, Jon.that looks way too easy to remove for Mick to resist...
I'll have to get my magnifying glass out and inspect the cylinder joint for braze.
Something else that this has highlighted is the fact that folks having their later Mercuries reblued run the risk of creating a porous breech in their cylinder by the hot bluing breaking down the sealing compound on the breech plug threads.
Ideally, to have a Mercury reblued I'd be looking at getting the plug and cylinder blued separately and then assembling them with Loctite afterwards.
All the best Mick
