I don't have a dog in this fight, but (as usual) find it hard to keep my mouth shut at times. A manufacturer would be setting themselves up for a real liability problem by building a hull for an unresearched powerplant. Home building or custom building would get you whatever your dollars want. Builders like Ranger and C-Dory offer specific models; deviation from those models results in more costs and manhours.
There is a reason that manufactures state that some modifications will void the factory warranty. Hounding them won't change that. If you called your local Chevy dealer and said you wanted a Duramax in an Aveo, they'd tell you "no way", also.
The 21 tug is a nifty boat and built for a purpose. Here's an article about a couple of them that made the trip up the Inside Passage. Very capable small boats.

Buy the right boat for the mission. These aren't speed boats, and the horsepower cost to get a bit more speed out of them isn't likely something that their market is interested in. It is what it is. There are other boats that size that will go faster. For a production boat, you pay your money, you make your choice. You want custom, you go to a marine architect/custom builder. Jeff is certainly a can-do kinda guy... within reason. When he was still at C-Dory, I wanted our boat to have a 25 foot folding mast, a cat-rig sail, a telescoping keel, and a kick-up rudder, so I could get 100 mpg. Yeah, I'm kidding. :wink: But if I decided to add that stuff to our boat, I'm guessing that besides voiding the warranty big time, it would also cream the resale value. And you can be darn sure the factory wouldn't have a thing to do with it.
Good luck finding or building the boat that best fits your needs.
