Loose pylon 77 Ski Nautique

My Tique had the same slop but it was due to CC not using some decent non rusting components. I cleaned up the pin and the socket, used mold release wax on the pin, poured thickened epoxy into the socket, set the pylon's pin into it and allowed the epoxy to kick.

While not quite the same boat I'm sure the construction is much
the same,after all they are both wood and only 8 years apart.
Mine was bad too seems all the water on the floor must try
to drain thru there and start the rot.I replaced it a number
of years ago when I pulled out the foam and is still in
excellent shape. This picture was just taken the other day
and I just put the floor in yesterday so I can't measure the
size,I'm guessing 2x10. Stringers were fine so I just put in
the pylon mount.Hope this helps-

it sits in a cup glassed to the hull and bolts to the floor with four bolts. Not a lot of support there. I would say that you should be looking into floor and stringer rot.
