I had the same set-up as you have now. The quad IV OT would be the prop I would get. Again, talk to Todd as he had me raise my motor a little bit because it is a 4 blade and has more blade area in the water at any given time compared to a 3 blade. Make sure you talk to him about the vent plugs because I had a little too much prop slip on hole shot and plugging 2 or 4 holes really helps depending on your individual needs. Great prop as it carries a load great and has plenty of top end.
