HI Brian, I had a LF38 (hull #4) with the same issues you're complaining about. Inefficiency while motoring, almost non-existence reverse. I installed a fixed pitch 3 blade prop. While it did help with motoring, reverse was not much better. On my new (to me) LF39, which came with a max prop. All I can say is wow! What a difference. motoring forward is better than the 2 blade and about equal to the fixed 3 blade. Reverse is a whole new world. That being said. I had the Paragon transmission which I could leave is neutral while sailing. Letting the prop freewheel. I think the dimension for the fixed prop were 18x11. I was told you want 1 less inch of pitch over the 2 blade. $3300 for the MAX prop is a lot swallow.I hope I answered at least some of your questions.
Doug here are a couple of articles on prop comparisons https://www.yachtingmonthly.com/gear/folding-and-feathering-propeller-test-29807 https://www.practical-sailor.com/issues/44_2/features/Folding-vs-Feathering-Props_12354-1.html https://www.sailmagazine.com/diy/why-low-drag-propellers On Sun, Oct 20, 2019 at 7:36 AM Brian Davis via CnC-List < cnc-list@cnc-list.com> wrote: > Good day fellow C&C'ers, > > I currently have a 2 blade prop on our Landfall 38SL (1980).
