Ok, I don't care whether I use M12 or unf bolts. The tohatsu manual says M12, but if unf will be cheaper/better then I'll go for those!
I had a look on the site richard posted but there doesn't seem to be high tensile stainless bolts listed...unless I'm looking in the wrong place?
So what do I need? if Mark's 140 is bolted on with 1/2" unf ss bolts then surely that would be ok for me? Are they high tensile mark?
The bloke at kevin mole said that if you don't use high tensile bolts, the threads can go.
I'm more confused than I was before
Thanks for the advice.
