[C320-list] Martec Folding Prop

[Warren Updike]

Jeff, let me begin by saying that I'm no expert just an owner hacker.
Things prop related can be complicated, especially in re. proper sizing.
So, I'll just say that I'm hard pressed to think that any appropriate prop
that will fit in the existing space would be too heavy for a bronze shaft;
providing, of course, that the max clearance between the strut and the prop
hub is no more than 1/2 the diameter of the shaft (1/2" in our cases with a
1" shaft.)  
Still, forewarned is forearmed and I'd look for opinions from the mfgr and
builder.

Thanks for the advise on the prop, we'll try the 14".  However, Tim brought
up the point on the brass shaft being too soft.   We do have brass, not
stainless steel so of course I'm concerned about bending.  Are there others
out there that have a Martec 14" prop on a brass shaft and had any issues
with it?  Thanks for your help.
