Anyone had problems with their aluminum pipes cracking?
A couple of weeks ago running offshore in 2-3' seas (closely packed) we noticed movement on the hardtop. Wasn't really running hard...approx. 27mph and ride was not bad. Later when we returned home, we saw where the front mounts came loose. Remove bolts cleaned up and recaulked and retightened all bolts. Added some extra SS washers since the single one seems too flimsy when tightening up on the cabin carpet.

Anyway, later when cleaning up the boat, I found 2 cracks near the top on the rear most vertical pipe, just under the welds on both sides.

Talked to Marine Fabricator and they said if they come loose, they will crack. They actually knew where the cracks were when I explained to them the front was loose! So sounds like this happens often enough for them to know about it. Told me to always check and retighten all bolts at least ever 3-6 months! I didn't know that was a problem, so now I am in the know and will try to keep them tight.

Will take it in this week and drop off to get the cracks repaired.

Searched around and don't find much about this issue......
