James, I have the Same boat!. '76 30 TF repowered in 2011. I viewed your Prop Size PDFs and really appreciate the data. can you confirm that this was done with 18x20 3 blade props. if so ... this is the answer i've been looking for. I am running 17 x 17 3 blade and i have a spare set of 4 blade. but feel the boat just doesn't go as fast as it could. several friends feel the same way as when we run with a little gear, gas and water we only get to 16 knots at 3100 rpm. i really feel we should be at 16 at 26-2800. as it appears you have reported.
The 2018 Chris-Craft Commander Club National Rendezvous is in the books and it was a great time!!
The city of Mentor, Ohio and the Lawnfield Inn & Suites were wonderful hosts. A special Thanks to Rob Kneen, the local member sponsor, and Char Pike for the hours of hard work put in organizing and coordinating an amazing weekend.
The Rendezvous Photo Albums can be accessed through the links below, as well as, under Library, Photo Albums. We will continue to add links to other albums as they become available. Also below, you will find links to a couple articles written for the local newspaper.
