3 years ago i bought a boat with that same set up. It sucked everyone was knocking heads. Sideways bench seats dont work. They need to be in the back of the boat, when they run down the side of the boat your head is like a wet noodle, it just flops around. Espeacially the person in the middle, needless to say the next day it went to the upholstery shop and was done up right. My boat has a gas pedal, I use it !
