Hmm, that'll make me think twice about installing that bracket and brace for the seat back, thanks for the info. I got my FAE early last summer and actually installed it while the boat was on my lift sitting on my paddle board, lol. Mine installed over the factory exhaust flange and it has a stainless steel tube brace that goes from the exhaust to a bracket they sent that attaches to the drain outlet. We had to cut that thing down quite a bit, the tube brace that is, to make it fit. When I sent them pics of the final install, they said they messed up and the brace was on the wrong side. I never changed it as it worked, has been solid, and has never moved. Other than going through a few cutting wheels and dropping a screw driver in the water, we had it done in right about an hour
