Boat is 1990 Ranger 365V with a 1990 Evinrude 150XP. Prop is OMC SS painted black 14.25x23. Centerline of prop is 4.5 inches below bottom of boat-looks like engine is where the manufacturer put it. In cold water runs 60 mph, no gps, at 5500 rpm WOT. In warm water barely gets to 45 mph and can easily rev engine over 6000 rpm.<br /><br />So I am looking for a prop. I also have access to 5.5 inch jack plate but am concerned about clearance between steering and top of transom - engine would have to come up a couple inches to clear transom when engine is tilted up.<br /><br />Thanks
