This sounds like an engine that just has not been run for a while. With the engine sitting a while and stored properly, it may take a little more time to get things cleared out of the system.
A couple of things that can be done have already been stated. Replace the fuel filter, and then add a can of seafoam to the tank so the carb/injectors get some deeper cleaning while you run.
There is no need to run premium fuel in the engine...that is just wasted money as the engine being a 2014 will be designed to run 87 octane. This fuel just by design will help to clean out any other "stuff" in the engine and ultimately will keep the engine clean once any contaminants are loosened up and burned out.
If possible, get a can of pressurized seafoam. A good thing you can do is once the engine is warm, spray some seafoam directly into the throttle body intake while the motor is at a high idle (like 1500 RPMs) ...the motor will start to sputter a bit and white smoke will start coming out the exhaust. Continue to do this for a few minutes, then spray until the motor dies. Once the motor dies, spray a bit more in, then let the engine sit for an hour or longer. What this process is going to do is clean the combustion chamber of any possible deposits, build up, etc. that might be in there. Take the motor out for a good spin and get it up to speed...burn out all the crud. When you first start it up, it will blow a lot of white smoke. Don't be worried about it, it'll subside.
At this point, the engine should be running a lot smoother if it was gunked up at all. After this process is done, it definitely would not hurt to replace the spark plugs, if for anything more than preventative maintenance.
I'd also suggest carrying an extra fuel filter as well. If the boat only had non-oxygenated fuel running through it, there could be a bunch of contaminants that could let loose and clog a filter, causing poor idle, poor acceleration, etc. It would be the first thing to replace if the engine sputters.
My gut says its just a dirty engine...
