I’m looking to replace existing seat on my 2006 year Trophy pro, WA2002 model. I’m trying to find a swivel chair that can be switched out to get rid of existing chairs which do actually turn, but only into a few locked positions, and are extremely tortuous to get them out of facing forward position. The passenger chair is not bolted to the deck, but sits on top of a frame, which make it trickier to switch out. Any ideas or experience with this issue is welcomed. Thanks for looking.
