I will not dispute what you say, I have experience with an underpowered boat (my first 18' open bow runabout that I bought).
I don't boat the way many power boaters do. I come from sailing, so putt-putt is fine by me. One advantage to the 5.0L is it brings the price of a bigger boat down to my level, without compromising the quality/condition of the boat. I wanted the 5.7L with at least 300 HP on this size boat, but the rest of the deal was an overriding factor. I'm not looking for resale... as you know, "resale" and "boat" are dichotomies. With just the intended use of the boat (retired wife and myself), the boat will not be loaded down or pull a skier. I've had this size engine with the DP before in a 23-foot cuddy (50 fewer ponies), and it went as fast as I care to go (over 40 MPH) with my then family of 5. I pulled skiers, tubers, knee boarders, and wakeboarders - nobody complained. This boat is about as fast as that boat (it cruises on plane at about 3300 RPM)... it's just slower out of the hole. Slather the rear with trim tabs and it punches out just fine. I have the performance graph for the 270 HP 5.0L on my boat (courtesy of boattest.com).
I have a friend who had a boat slightly larger than mine. His rig was underpowered, but it had the Volvo - so he took a chance on swapping from single screw to DP. Just the drive change alone made it a whole different boat - he was finally able to punch out through the planing transition and attain a much higher top speed. He also gained a lot of acceleration.
As a DP owner, I assume you've had single screws before - and once you experienced the difference, you likely don't want to go back.
In road vehicles... I've experienced many gasser 7.4Ls and 7.5Ls, along with just about every gas V8 ever built. I hate, hate, hate, the power to fuel ratio for that sized engine - but maybe I had a few duds... I dunno. I am now a dieselholic.
