So I've been attempting the replacement of the top-mounts on my 85AET Yam 2 troke... And until today it was all going quite well. Got the powerhead off with only one sheared bolt, and since it was already pretty much out of the threaded part when it sheared that seemed to be reasonably good going.
Today I tried to get the clamp at the top of the leg which hold the mounts in place off, and all three bolts sheared like they were made of creamcheese:
I've also managed to shear one of the bolts of the lower mounting clamp:
So I'm looking for an engineering shop or someone with a pillar drill, in West Yorkshire, or at least 'the North' who can drill these out and fix the threads for me. Any ideas? The leg is off the boat right now so I can take it to wherever it needs to go.
