M_Boats: Transom mounted ladder on M17

I am installing a permanent, transom mounted, fold down, 4 step, SS ladder on my 1976 M-17. It mounts with 2 clips at the top & 2 round stand-offs at the bottom. The clips have 2 bolts each. The stand offs use 3 bolts each. All the fasteners are ¼”-20 bolts, lock nuts, & fender washers. I’m curious if the group feels that the transom needs to be reinforced for these attachments. My transom above the cockpit seat is 1.125” thick fiberglass and plywood (I think) core. This seems to me adequate for the clip attachments. I think the transom gets a little thinner below the seat, but I think it still should be adequate. What do you guys think? Thanks – Gary Froeschner
