Does anyone know how to remove a MARTEC prop? There isn't a nut
holding it on. It looks like it screws on with a thin cotter pin
holding it in place (Conventional thread? Reverse thread?). Is this
correct.
Thanks,
John

I do not have any experience with Martecs, but I suggest going directly
to the mfr'r on this one. I wouldn't want to bung it up experimenting.
Good luck.

It's certainly not intuitive, but here's what to do:
1. Remove the two cotter pins retaining the blade pivot
pin and remove the pin and blades, noting the orientation
of the blades to one another and to the hub.
2. If you now look into the back of the hub you will see
a square recess with two more cotter pins projecting into it
from the outside of the hub. Remove the cotter pins.
3. You can now use a square socket wrench extension and
ratchet handle to remove the retaining nut. My prop takes
a 3/8 " wrench; larger props may require a larger size.
4. Once the nut is off (RH thread) you can pull the prop off
the tapered propeller shaft using conventional methods (gear
puller, etc.
5. The prop hub is keyed to the tapered shaft, so you would
have very poor luck trying to "unscrew" it.
One advantage to this weird attaching arrangement is that it
makes it less than obvious how to steal the prop.
Hope the above is helpful.
