I also noticed the boat does not loose speed as easily when it hits waves and has more braking power when thrown in reverse. The water was like glass and I was doing 6.8 to 7.2 most of the time. I recently went on a weekend cruise and had no wind on one leg and motored for 4 hours. (I used to be at 5.2 and 5.8 at these revs) I can cruise comfortably at 6.2-6.4 at about 2800 RPM. I have picked up about a knot more speed in all conditions under power. The very first time I put her in gear with the new 15X12 prop I was impressed with how much more thrust there was and how quickly she accelerated.

Just want to follow up now that I have had a chance to see how the rebladed prop worked out. Martec denied any responsibility for the failure, but did completely refurbish the hub and installed two new blades for their standard price. I can't wait to get the Martec prop back on the boat. I have to pay a 6 second per NM penalty for using the folding prop but it seems well worth it. The boat is noticably slower both under sail and under power.

This year, one blade broke off and I had to install the old 3 blade 14x8 fixed blade prop while I dealt with Martec. When I bought it last year, it had a Martec 2 blade 14x14 folding prop on it and was very competative in club racing. I own a 1982 S2 9.2 with a Yanmar 2GM engine.
