Lou I can't help diagnose much but do you have a local prop shop? They can tune your stock prop or if you want to start over with a clean prop try Turning Point Propellers. I really like their stuff out of the box and with the aluminum a local shop can rework it for pitch, cup, etc., quickly and cheaply.
TP Props for you motor is a larger diameter 10.375 available in 11 and 13 pitch. Iboats has the TP Hustler in 13 pitch for $82 and Amazon will have them also.
Sorry I can't add much but an aluminum 13p with light cupping sounds like it should fit your needs.
