Pulled the motor last fall and I can't find the bolts. I have the mounts, fiber washers, springs, etc. Was wondering if I could use just a regualar grade 8 bolt or if I need to order a bolt kit? I'm hoping to put this thing in this weekend as I have already been delayed twice and I'm hoping that these damn bolts won't hold me up another week. Does anybody know if I can use other bolts and if I can how long and what size are they?

I'm assuming it's for the '87 magnum you have listed on your avitar. It would be part #10 in this diagram merc number 10-97934.

And in this diagram it says it's a 1/2" 20 thread x 5 1/4".

I would think it would be fine to use a regular grade 8.

Aren't those the funny shaped aluminum bolts that have a ronded end on them and sre only threaded on the end? I would think it would be very ifficult to find a "standard" bolt that would match very well. If you lived down the street, I've got a set or two laying around...

X 2, I'm pretty sure your going to need to find or order the correct bolts.
