I wanted to share my experience in hopes it will save some other rafters the heartache I have experienced.
I just returned from our annual Rogue River trip in Oregon. When we pulled off the river I was shooting the breeze with a gentleman for a while about boating equipment and such. I explained I had a couple things I would like to do to my new to me Maravia.
He directed me a couple hours North to the local river shop that had a frame consultant on hand. My wife and the dog made the trek and had a couple small things welded up that needed done. The gentleman informed me I had the wrong size boxes in my raft and they were applying too much pressure to the tubes and the welding was rough on the joint near the tube. I bought this package about 3 months ago used but the whole thing is only one year old and was like new. He offered to install the correct boxes and put on tabs for 400.00, no way was I buying into this. Afterall I was on the journey home and my madcow boxes are like new.
Two days later we are unloading the boat, we remove the boxes. I will be damned if I didn't find the box he warned me about worn through my tube. Now I am kicking myself for not heeding his warning and just replacing the box, he even offered to smooth out the weld and I declined in a hurry to make for home.
I advise any of you that have ill fitting boxes to check them. Also if a professional frame guy tells you something you might take the advise. I have no idea what this will cost to fix and how it can be done. I am looking at a trip to Boise now for the repair.
