That's less than half what the MSRP on a comparable Max-Prop would be.
That being said, I like my Max-Prop and would generally only consider a
Gori in its place.
Someone here has advised of a feathering prop which doesn't need the pitch
adjusted? Kiwi-prop? I can't remember. I was quite
Yes, compared to the old fixed 2 blades. But maybe that old prop needed to be
rebalanced, who knows. My prop shaft is aligned with the keel. I believe the 3
blades makes a difference there. There is always a blade that has less
turbulence from the keel. At least that is was I found as an
Bruno, did you find there was less vibration with the three blade prop?

50$ freight charge. Plus the

Hi Dave,
For most marine gearboxes the output flange
bearing is a thrust bearing. There to take up the shaft thrust fore and aft.
Try to move that output flange forward or back,
it will seem like it's stuck fast. discalimer about some nimrod not attempting this while engine is running>
Hi Mike,
It sounds like you just won your own argument.
Cheers, Russ

I had an exciting freighter experience this past weekend.
I went for a leisurely sunset sail with a couple of friends on Saturday
from San Francisco (where I had parked the boat for a few days) across the
bay to Emeryville (where I am permanently berthed). We were probably about
a half-mile
Here's the link to the video of the idiotic sailor who tried to cross in front
of a freighter during Cowes Week in 2011. The skipper was fined GBP 3000!

Rick / Mike:
I think we have an over zealous 'Pilot'.Last Summer, I witnessed
something quite unusual.an out going 'pilot boat' around the Point
Pleasant Shoal mark turned around and blasted a sail boat in the path of
an outgoing container vessel which was still back by George's
Mike,
We heard that from our side of the harbour.
Were boats actually in the way of the container ship or was the pilot boat
overreacting again.

Halifax,
I like my MaxProp 2 blade. Instant bite in reverse, better than a fixed prop.
Feathers easily. Leave the gear in reverse. Maybe a little more drag than
folding, but it works well. Also, it's adjustable, and I've been able to
maximize my engine performance over the years (got to be out of the
For me it was a priority to buy a nice prop.
I was loosing sleep over the drag of my old fixed prop to my boat that i wanted
to race, and was also going crazy earing the prop free spin underway. I had to
do something and choose a Flexofold that was cheaper than a maxprop.
My flexofold will
Mike,
I will get back to you tonight with the price of my Flexofold 3 blades. It was
not chead and i remebered i had to pay a ridiculously high custom clearance fee
to UPS, I hate them since.
I was convinced to go 3 blades after reading a lot about prop balance and
vibration. It is more
I believe, because while sailing in fwd (dragging the prop along) there is
"negative thrust" on the clutch cone bearing surfaces, allowing the clutch
to slip. (when powering, the prop is instead pushing forward, loading
those surfaces)In neutral, the clutch cones are centred, freewheeling,
Good to know. On mine if I put it in gear I need to start the engine to get
it out as the pressure while still sailing makes the shift lever very stiff
to move to neutral and that can't be good for the mechanism. I do not have
a folding prop. With a spinning prop, while not as good as folding, the
Our Westerbeke manual recommends transmission in the neutral position, but goes
on to say that leaving it in the forward position will not damage the engine.

+ 1 on reverse while sailing specifically for folding or feathering props.
If you leave it in neutral or forward it will freewheel and keep it from
folding. I don't know exactly why it still freewheels in forward but I do
know it does.
As for fixed props, Yanmar is very specific:

should have shaft aligned such that the blades are horizontal so that they stay

So if the shaft is aligned

It seems that Pilot boats use horn signals and that Container ships trump all
vessels.
Last evening during a Wednesday race with 30+ sailboats in varying classes in
light winds the Pilot boat leaving the harbour stopped mid fleet turned
backwards and repeatedly sounded their horn for a
Why is the prop turning if you are in gear?

Gary,
I have a Flex-o-Fold also, and if I don't "lock" it, it will continue
to spin. I use reverse.
