I own/run a 18X52 ProDrive rig with a 32hp PD on the back. I'd say the PD will suit your needs well, but you will need the rock guard installed which adds more weight. The PD rock guard isn't like most other rock guards. It's got 4 other "skegs" built on the regular one. They had one in da back of da truck at Reelfoot a few months ago and I thought I got a pic of it, but can't find it now. I'll holla at a few friends to see if they got one of it.
As far as the "tripping hazards", I thought the same thing when I saw there boat, but for some reason, I don't even realize they're there when I'm in my rig. That's hard to explain, but its da truth.
Weight might be an issue with a 32hp on a 16ft boat. I would suggest at least a 17ft but think 18 is optimum. As far as width.......that's more difficult to suggest. 54 was too wide for me, but 48 was too narrow. It mainly depends on what type of load you plan on carrying. I usually always have 3 people and two dogs with me, so I wanted a little wider boat. If you won't have much load in your rig, the 48 would be fine.
I'll try to find that pic of the PD rock guard. I promise its one bad dude!
