Engine bolts.

Do mercury do an engine mounting kit? IE a bolt set. Metric fine 12mm. About 100mm long.
Usual sources proving unsuccessful.

I replaced the bolts on my opti and found Mercury just sell them as individual bolts (and nuts) seperately in differing lengths to suit the set up and thickness of boat. Stupidly expensive however . I added a couple of extra large washers to the bottom and a support bar between the two top bolts to spread the load - worth doing IMO...

I managed to drop one in the river ..but found RIBSMARINE & Marinautic had them on the shelf.

Recently bought new bolts from Rob @ Blackdog.
Pretty expensive, but seem to be the job well...

I don't know if this is any use, but when I was looking for some stainless bolts to mount my engine I got them from here, price seemed OK and deilvery was fast.

I would've thought merc bolts were 1/2" UNF

The ones that came with my mariner 50hp were high tensile, not stainless
