I see a lot of my boat in yours, good job. I like your reverse setup and plan on incorporating something similar.

Br549, VERY nice work, man!! =D> You have some serious fabrication skills. I REALLY like that flange you made for the pump intake duct, that's how I should have done mine, it would have been a lot easier for sure.

I have no experience with running boats in these types of rivers, other than paddling a raft or a kayak.
However, based on my observation and experience, IMHO, going UP isn't the real problem, at least as far as the danger level is concerned.
Going up, you can see the obstruction or rock ledge, and can read where the channel is to go through it.
Coming back DOWN is another story, those rocks and drop-offs are not visible until you are on top of them, and by then, it's too late.
I have never been brave enough to take my boat through any kind of rocks or lateral steps, mainly because the rivers where there are rocks, are a long ways from home, and that's not a good place to have problems. But there is a set of rapids a little closer to home, above Florence on the Pee Dee River at Hwy 34. They are exposed on lower levels. When the water gets back down, I plan to go there one day and do a little bit of 'training' by running through here a few times. After that, I may try a river somewhere else.

Mine's a 1648 SV Duracraft, with a 160 HP Yamaha MR-1 High Output 4 stroke. I'm running a Yamaha XL1200W pump, and a Solas YD-CD 13/19 swirl impeller. My boat has (2) 11 gallon fuel tanks, for a combined total of 22 gallons. On average cruising speeds, it burns about 3 GPH, or about 5 MPG, either way, this is how it averages out on the fuel economy, which is waaaay better than it was with the old 2-stroke engine.
As I said before, though, your approach to installing the intake duct is MUCH better than mine. To begin with, you have the boat upside down...and that makes welding a helluva lot easier than trying to do it overhead! Also, the flange you've made will deal with that funky angle of the lower edge of the intake duct, how it starts out 3/4" of an inch thick at the back end, and tapers down to nothing at the front. I had to make that same shape for the pump to fit in my boat, but mine did not go very easily, as it involved a LOT of grinding!! Yours will avoid all that BS.
