well, you need to set your idle stop screw so the motor will idle at 600-750 in gear, in the water. with out knowing the size boat, 14' or 30' there is no way to tell if you are propped correctly. 5500 is not bad closer to 5800 would be better, which means a prop change. post this in the prop forum.
