i think the drag hydro(outboard steering) is a little smaller but still can fit 2 seats. not positive, used to have a outboard steering shovel nose with 2 seats in it. the seats were very close together, but worked fine. also had a ski hydro(inboard steering) with back to backs, but seemed to have more room. its not that hard to move the steering over just some time and alittle money. you will have to get a new chain or longer cables , depending on what type of steering box you have, and cover the old center hole up(good place for a tach).
