Changing the motor height is not a tough job. I've helped, and seen it done in parking lots. You'll need the trailer off the tow vehicle, the wheels chocked, and one or two friends. Lower the tongue jack, and place a board under the skeg. Raise the jack until the weight of the motor is just off the transom. Take out the lower bolts, and loosen the top bolts. Have your friend hold the motor steady, and remove the top bolts. Have the other friend lower or raise the tongue jack to the desired hole. Put the top bolts in, put on the nuts, snug them up, and then the lower bolts. Don't foget to put new marine RTV on the bolts. Torque all the bolts, and you're good to go.

I don't think that 4 stroke will ever have the hole shot of the two stroke you had on it, without sacrificing top end. Not a knock, but just so you are prepared for that.
