Had Mark Croxton work a prop fror me; B&B, a little cup, etc. and got to 5800 rpm's and 74.3 GPS (2 people, full load) 2 weeks ago. Dinged up all 3 leading edges earlier this week on first morning of recent trip. Prop not too bad at all but now only running 5500 -5600 and 71.2 with similar load. If the prop is not it (on the way back to Mark) what's next?? Still running on same gas from previous trip. No water in fuel separator (Racor). Thoughts??
