I would try the prop that is on it first and see what it does. The jackplate will be a nice feature for you. I would set the motor so it is about 2-1/2 to 3 inches above the lowest point on the transom and see how it works. What the jackplate will do is two-fold....it will get your motor running in cleaner water (no bubbles from the hull to disrupt water flow into the prop) and it also moves the center of gravity more to the rear which makes trimming the bow easier. You will find you will not have to trim up as much to get the bow to lift. The only thing you might want to consider when using the jack plate is to get a water pressure gauge (they are around $35 or so) just to be sure you don't get too high and start losing water pressure. I believe staying above 10 psi is where you would want to be at to keep the engine safe from overheating. If anything it is a nice feature to have since it can also give you some insight into when a water impeller change could be needed.
The prop itself has a smaller diameter, but higher pitch, so you might be pleasantly surprised at how it might work. My gut instinct says it will be a touch high on the pitch, but that motor should have a little higher displacement than my yamaha 90 2 stroke, so it may work just fine. Nonetheless, if it doesn't work, you should be able to sell the prop for around $150 or so, recouping some of the money spent on the motor. And..if you decide not to go with the jack plate, you could get another $70 or so from that, if not more...
Good luck and definitely report back on how it is going.
