1987 Seebold 20' Ski Eagle prop and prop shaft height
1987 Seebold 20' Ski Eagle has a 1987 Johnson GT 200 with a 4 blade OMC Shooter prop. I have read this prop is not designed to surface, but I might try it anyway. Max RPM is 5600 at 65 MPH on GPS. As it is trimmed up, while at full throttle, it is tight until enough trim then it loosens up and starts to porpoise. There is a very fine line between tight and when it starts to porpoise. The prop shaft is about 3 inches below the bottom of the hull. I was thinking I need a 3 blade with out the hub, chopper style and raise the engine to get more speed. I know many of the big cats porpoise but you need to power through it then it smooths out. I am thinking I need more speed to get through the porpoise. What prop and height works on these hulls? I know it needs a "Black" engine, but I have a white one for now.
