I guess SK answered that.

Bondo is still here helping out. Yep - Almost next door neighbors.
The reason I asked about the transom flexing or pod or both, is if you have plywood, it can rot and flex. If the pod is moving, the pod or the support crossmembers could be cracked. Or a combination of the three, we've seen that in the forums.
A funny thing happened a few years back, I am a mod on a DIY forum where Bondo is a member, I hit the wrong button one night and banned him, talk about red faced.
I got under the pontoon today and I did not like what I saw. In the photo above that Tommy posted, the outside floor support is the only one there on my toon. The is another one about 2 feet from the outside one which is at the end of the pod. I can not believe that one outside floor support is holding that 85 hp Rude motor up. There is no wonder it is bouncing, it can't do anything else except fall off.
One thing that really was not what I wanted to see, is a crack in each log where the weight of the motor is transferred from the floor support that holds the weight of the motor, to to logs. The cracks are about 2 or 2 1/2 inches long, but any crack is too many. Once I jack the motor up and install two large aluminum angles all the way across the boat and get the two cracks welded and the small stress crack on the transom, I should be good to go there. I will have the logs reinforced at those cracks.
Another thing I saw under the toon today was there are 4 upright guide posts that someone bent the dickens out of one of the trailer cross members when it pushed the guides forward at a slight angle. I will solve this problem with some added guides or a 12 foot runner to guide the toon on the trailer.
I apologize for the long post. I plan to replace the carpet on the runners, I bought a thinner outdoor carpet. Will that be OK for the runners instead of the thicker carpet? I also suspect the wood in the runners is treated, how can I seal the wood before I install the new carpet? Sorry for the Book.
