That's a competitor website and is not allowed

Its best in this case to list what drive (VP, OMC, etc) and then list the part number being listed. This way we will have a better chance of looking up what your needing

Sorry I'm coming up empty. Was also thinking someone else would see that had more knowledge of the OMC. It would be SAE standard size bolts, so measure the diameter. It should then be

5/16-18 thread
3/8-16
7/16-14

The transom should be 2 to 21/4 thick, then add for washers, nuts and/or depth of housing

Ayuh,..... The Machinist oughta be able to figure it out, they're standard inch measure bolts,......

I'd think 7/16" - 14,...... Maybe 1/2" - 13,.....

Length is whatever ya need,.....

Gr.5s,... no need for gr.8s,..... SS is to soft, 'n corrodes anyways,....
