I'm looking to move into an aluminum boat with a jet so I can run further up river. I just looked at a leftover G3 1656 CCJ but they also had a 1548 MV with the floor and vinyl and side console all rigged up for a Yamaha but no motor. I'd pefer the center console as I like to stand up while running up the river. But I really like the size of the 1548 but it didn't have the tunnel. So my question is, is there really a big difference in running a jet outboard with the tunnel vs without? Obviously, the tunnel would allow you to run the motor a little higher which would keep it protected more. I'm not looking to run this boat around and pull skiiers or tubers, I'll be out by myself 99% of the time and usually motor upstream to fish or relax and then float back down. And can I run a 60/40 jet on the 1548?
