I think I've got about equal hours on the main & the aux this year!

Since Feb It's certainly done more miles on the trailer than afloat......

Such are the hazards of buying a secondhand engine of unknown history......
Having said that, on the plus side, I will soon (well, OK, when I get 10 mins to take & upload the "after" pics) be able to post a "Humber refurb - part 1" thread, and if all goes to plan (i.e the cyls don't need more than a 30 tho' bore!) follow it with a "Merc rebuild" thread.
I'll probably get it ready just in time for the first snow......
