Known length and thread size?

[millbros]

Does anyone know what the exact length and thread size of this bolt? $70 each is kinda pricey.

Not finding actual size. You can't take one out and take it to a hardware store?

i would if I actually had 1. Both bolts backed out and are missing in action. Lucky my whole outboard didn't fall off the back of the boat.
