I will chime in if you guys dont mind? I own a 16 ft lowe roughneck. THe boat is an allweld jon. There are several things I like about it. I like to hunt out of my boat as well as fish. I am usually by myself and had to be able to manuver the boat alone. My lowe is very night and runs very shallow. I can launch and load by myself very easy all year long. The lowe has a tunnel on the bottom of the boat that directs water to the jet. This is nice because it keeps the motor above the bottom of most of the boat. The stern is all weld and jacks the motor up. I run a 90 hp Merc on it. I like the 90 because I do duck hunt out of it and it can get heavy with the blind on, decoys, dog and dead beat buddies that never pay for gas. LOL just kidding. That 90 gets it up and going. It is also night when the river is up this time of year. I have added a spray bar and wings on the jet to direct more water to the jet. Does it work? I dont know but can hurt. I love my boat and used it all but Feb last year for hunting and fish. I have two little boys that love to fish and so it is great for that. When they want to go....you go. Well thats my two cents.
Good luck and safe boating
PS get a tilt on the motor and a GOOD Bilge if your going to hunt out of it. Dogs bring in alot of water.
