Hi
I had a DF140 and it was/is a fantastic engine. However, I was "advised" that it only produced circa 125-130HP. As a consequence I would suggest the larger capacity DF150 or even the DF175.

Don't have any answers on the Suzi-wong, but have dived from a Redbay 6.1, single console/jockey for years. She may be lighter than the rest of the 6.1's as was laid-up by Tom McL as a round Ireland racer and converted to diving config on resale. She is fitted with an Evinrude 115 ficht and makes about 33-35kts with 3 or 4 up, max fuel and light kit. She cruises at about 20kts with the load you describe. I'd be guessing that a bigger engine run at lower revs might be the best way to go. If you're buying new, I'd take Redbay's advice - they fit a lot of Suzi's and rate them over o/b Yamahas (and they sell a lot of inboard Yamahas)
