I believe the shaft / prop pin location is more important with folding propellers than feathering propellers. For long races (like Transpac) the orientation of a two bladed feathering prop would be monitored.
For long offshore races on boat equipped with the non-geared folding props, just before the start on of the crew would dive over the side to place rubber bands around the blades to hold them closed. With two bladed MAX props the shaft would be aligned with pre marked lines indicating the prop was lined up with the strut. Calypso has a three bladed MAX prop and we do not make any effort to align the shaft. Maybe I should look into marking it to put one of the three blades behind the strut for those light air days.

I had sort if assumes that once feathered, the drag would be the same irrespective of position. You must also keep a lot less junk in the lazarette than I - making it easy to access the shaft! I do know that I will often shut down the engine while in neutral and then start feeling the vibration from the spinning prop. At that point I just put the transmission in reverse and the vibration stops. I have always assumed that the blades would feather at that time. -- Jonathan Indigo C&C 35III SOUTHPORT CT On Aug 9, 2013, at 20:20, "Jake Brodersen" <captain_j...@cox.net> wrote: > Jonathan, > > I position the prop to the blades are both retracted (i.e. the pivot > pin is > vertical) before we start racing.
