Imagine having nearly full thrust in reverse if/when you run aground.
Being able to get off quickly might save enough of your energy for
everything else.

BTW, we paid about $2k for our MaxProp just over a year ago. A few
minutes after I paid for ours, I chatted with a Catalina 38 owner that
got the exact same prop (16" 3 blade). [That's the largest prop they'd
sell me; we could fit a 20" with our clearance and would have gotten one

Where do you get a MaxProp? Know any place in Canada? (I ask because
these days it costs $100 or so to get ANYTHING across the border!) I
searched the web and all I found was Property Managers. The "1/2 the price
of the engine" came from the quote I got for an AutoProp: $3K. And the
engine is about $6K (About $8500 CDN).

(BTW: I'm not really concerned with reverse - after nearly 15 yrs, I've
gotten used to Far Cove's propwalk and use it to my advantage. But extra
punch in fwd would be nice!)

=========================================

If you like to sail in light air, you will not be happy with a 3
bladed fixed prop. If light air speed is not important to you however
that would be a good choice for performance under power.

I think we got ours from PYI http://www.pyiinc.com/ MaxProp
themselves are at http://www.max-prop.com/

You might try http://www.vicprop.com/sales.htm who are in Canada and
say they handle the MaxProp.

I don't think you will get an extra punch in fwd. As I understand it
(and I may be wrong), the reason that you get more reverse is that the
prop paddles are not 'cupped' or angled like the fixed prop ones are,
but are flat. The cupping is for maximum performance in forward gear,
and it makes reverse less efficient. If you have a flat prop, then it
is equally good in both directions.

The MaxProp turns the blade when reversing, presenting the same
"forward" edge of the blades in both forward and reverse, thus
providing a very good thrust also in reverse since there is no
compromise between fwd and reverse efficiency in the blade design.

IMO, the only "better" prop than MaxProp is the Gori
folding-feathering (or what to call it), but that's even more
expensive.

Agreement, from our experience. (Dang, I snipped my comment that our 16"
3-blade MaxProp was *nearly* as efficient as a 15" two-blade. Sorry.)

Another poster gave what I believe is a good site. Yell if that isn't
good enough

I don't think you'll get better punch in forward unless you're switching
from 2 to 3 blades or to a larger diameter, as the MaxProp isn't
optimized for forward though it isn't horrible.

Performance in reverse is an amazing improvement though. You have to
experience it to believe the difference. We spin on our axis so easily
that we've never actually *needed* an authoritative reverse to get
unstuck, but we haven't needed to spin to get ungrounded since we
switched. ('Course, that could be because I've learned not to get as stuck.)

Our switch was from 15"x2 blade to 16"x3, so we can pull stumps if we
need to, and our reverse power is only slightly less than forward.

The Luke is nice because its geometry is pretty much identical
to a fixed prop in fwd and rev. No poor performance in
rev like some feathering or folding props.

Agreed. My Luke prop has the exact configuration of a fixed prop
when in fwd or rev. No degradation in reverse. Feathers well too.
