I have a Kiwi-prop, installed 2008 when I changed
out the A4 to an old Yanmar QM20. I like it.
Chosen in part because I could swing the largest
diameter due to the way blades are mounted. Tip
clearance took advantage of the way the buttock
lines sweep up a lot in the area. A few extra
inches in (new) shaft length and I got a 17" prop down there. :)
The thing is a beast in reverse because it goes
full pitch (no adjustable stops) so I typically
just go a few boats lengths at most and pop into
neutral if I have to travel further back.
Great customer support if dealing with John in
New Zealand. I suggest going direct and giving a
pass on the Canadian distributor if you choose a Kiwi-prop.

Have you considered Kiwi prop? I donât have
the first hand experience, but the tests suggest
that it is in the middle of the pack for prop
walk and reverse pull and it is, usually,
substantially cheaper than the Gori or Max-Prop.
And, as usual, the best is to check the actual
test results, e.g. here:
<http://www.yachtingmonthly.com/gear/folding-and-feathering-propeller-test-29807>http://www.yachtingmonthly.com/gear/folding-and-feathering-propeller-test-29807.
Please be aware that the original test was done
in 2009, though I am not sure if much has
changed since. The same test is available as a
PDF from Flexofold web site (here:
<http://www.flexofold.com/test-results/>http://www.flexofold.com/test-results/).
I guess they liked what they saw there.
