That should be a good choice.
Not that you asked...
We have a vinyl 14' Sea Eagle, a hypalon 11' Seaworthy, and a 11' hypalon Avon. All have wood or plastic flat floors. Because it is a bit heavier to transport, the 14' only gets used when we vacation with the 2 sister-in-laws.
I also have a choice of 9.8, 15, or 18 hp 2 cycle engines. The 14' is rated for 40 hp. I've tried them all with the various boats. I no longer mess with the larger hp engines. The 9.8 hp is lightest. With 3 people in the 14' Sea Eagle and some weight shifting the 9.8 hp will get us up on plane. With 2 people we pop right up on plane with no problem. Dealing with older engines, I carry a Nissan 3.5 hp engine as a backup. (I'd hate to have a problem and know that I left a backup engine home.) Even the 3.5 hp will get the 11' boats up on plane when I'm alone. I haven't tried that with the 14' boat.
The newer 4 stroke engines are heavier. I'm not familiar with the 4 strokes, but I know that in 2 stroke engines many 9.9 and 15 hp outboards share the same basic engine frame. A 9.9 weighs the same as a 15 hp. Be certain to place the engine correctly when storing or the engine oil will go where you don't want it.
If you will mostly be just 2 in the boat I would go for a 9.8 or 15 hp engine. It will do all that you need for 2 people. The difference in weight/size when muscling around or storing the engine is worth it.
I made a dolly for moving the boat around and for launch/retrieval. It makes things easier. There are commercial dollies available. Another option is two swing wheels that fasten to the transom. My bother-in-law tried those. They work, but the weight isn't balanced at all. Picking up and supporting the bow of the can be heavy. BIL would often forget things. I coined "WUV me". Wheels up, vent open (fuel tank). He eventually went to a dolly.
If you decide to make a dolly be careful if choosing a DIY PVC pipe style. I've seen quite a few of those designs which failed during launch/retrieval. I used aluminum channel for the dollies that I built.
For general information. There are many other brands.

(Make sure that the handle kicks up high enough to make moving easy. If the design is straight, I suppose that a short piece of line with a PVC handle could be added.)

I think you'll love the opportunities that the inflatable powered sport boat opens up for you.
