Looking to lift my boat seat 3", it is on a 2 3/8" post. So far the best solution I can come up with is to buy 1" X 3" aluminum bar and drill holes through it and mount it between the seat and the post. The aluminum is 33 bucks a ft.
Was hoping to do it cheaper. The post are stupid expensive and I doubt I could get one long enough unless it was custom, again more than I want to spend. Any suggestions?
