Hello, can anyone tell me what the torque setting is for the head bolts on my 1988 Force 125hp? I am replacing the head gasket.
Thanks For All The Help,

Thanks,

force manf. manual says this... "torque bolts in sequence to 75 inlbs: then torque 50 in lbs at a time until bolts are torqued to 225 + 5 in lbs"

torque sequence:

17 18
13 14
9 10
5 6
1 2
4 3
8 7
12 11
16 15

Thats INCH lbs, NOT FOOT lbs.


225 in lbs = 18.75 ft lbs

You "could" use another bolt, but you SHOULD go to Mercury and get the right one.
You are gonna need a new head gasket anyway, as that one is probably crushed beyond use.

Subject of broken bolts has been discussed many times.
You can try the search feature looking for "broken bolt" or "bolt removal".
Removal depends on condition.
Drill it, then easy-out bolt remover.
Or weld another bolt onto it, then turn it out.
Or drill it out and re-tap the block.

Thank you guys for all the help. I was not thinking straight when I tried to tighten the bolts down. I was a little out of it considering both my cars were broken into the night before. I will order a new gasket and new bolts today.
Thanks,
Rich
