Last weekend I went to install a new three blade Indigo propellor and founds that although the old two blade came off easy, there was not enough room to install the three blade.
What I elected to do was to remove the lower rudder mount, which gave me just enough room.
Now I have to re-seal the lower rudder mount.
I could probably have disconnected the prop shaft, but access is tight in there and I prefer to avoid the contortionist positions lol.
I'll post some photos soon and a report on the new prop's performance.
I'm hopig that I'll get everything that is claimed by Indigo Electronics.
