I have a F39 Express with the original two bladed prop. Anybody
change these out for a better cruising prop? Not worried about
saving a few seconds on a race, but better preformance while
cruising. By the way I have the Yanmar 4Jh for an engine.

Have an F-33 not a 39 but changed the fixed prop to a 3 bladed
feathering variprop. This can be adjusted (externally) for separate
pitches forward and reverse unlike the maxprop. Its also a very
short hub and fits easily in the space of the old prop with no shaft
cutting.
