I found the pic of the keel cable pulley adapter you made, I think, in an earlier thread/ page.
Is the part sticking out of the hull under the floor just threaded into the hull?
You mentioned welding the nut on the bracket to fit the cable guide and another nut welded on for the forward mount?
This is a complicated fix for a newbie like myself.
There are enough people having this problem to warrant a complete start to finish video or pics to link to in forum.
