Shortman Headed into my fourth season w/mine on a Pearson 34 with a Yanmar 3GMF. Quite happy with it. Greatly reduced walk. Much better reverse. Chipped one blade corner on a log first season, have not replaced because damage small, BUT it is replaceable. A little grease every spring. Deal direct w/mfg. & they're very responsive.

brokesailor I must apologize to the group. I have a Gori prop not a Kiwi.

sailIC Before everybody think the Kiwiprop is the best thing since sliced bread, below is the thought process I went through before buying one. Here is to me a simple summary of the different pros/cons by prop type

Fixed
Pros: Best engine performance, reliable, cheap
Cons: Huge drag when sailing

Folding:
Pros: Lowest drag when sailing, Medium price
Cons: Poor engine performance especially reverse, reliability

Feathering:
Pros: Almost as low drag as folding, almost as good by engine as fixed
Cons: Very expensive

The really good thing with the Kiwiprop is the price. I think thatís the main reason why you buy it. I do think other much more expensive feathering props has slightly lower drag but the Kiwiprop is huge improvement over fixed.

When I got it I was also very impressed by the simplicity of the design. Aside from braking the replacable blades, I cannot see what can break.

I cannot understand why the propwalk almost disappeared. It might have something to do with that when the blade flips it will have the same leading edge both forward and reverse. Also (if I remember correctly), the reverse pitch (not adjustable) was very high. Might have something to do with it, but it did work.

The only negative that surprised me was that the propeller rotated whilst sailing. Cannot understand why it did with freely feathering blades, but it has to generate some resistance. Easily fixed by putting the gearbox in reverse, but I heard of problems if you have a hydraulic gearbox.

All in all, I would definitely buy it again.

night0wl Just ordered the Kiwi Prop for our Beneteau 343. We have pretty bad prop-walk, so I'm hoping to get cured on that. Also, in 10-12 knots of wind, I usually make a little over 4 knots SOG with my fixed 3 blad prop. People have called my fixed prop the equivalent of a bucket being towed behind us


Will report on our experience when I get Jendai back in 2 weeks after our haul-out.

sailjunkie One of the previous owners had installed an L/H pitch Kiwi Feathering Prop on our 29 foot boat. As others have said, no problems.

One further note, there is minimal prop walk in reverse and none in forward. It is early days for us, but so far, so good.

brokesailor On a Hunter 36 I replaced the stock fixed three blade with a 3 blade kiwi. Best thing I ever bought for the boat. Prop walk is completely gone. Under power going into the wind up the Potomac at 20-25 KTS I was doing about 6 KTS. With the old prop I would have been lucky if I did 3 KTS undr those conditions. Sailing performance has also improved picking up .5-1 KT.

sailIC I'm actually the original poster and stumbled over this post on another search. I did move ahead an bought a Kiwi prop, and even if I sold the boat four years ago i did use the boat on an 2 month cruise with it.

Overall i was pleased with the prop. As expected, the sailing performance improved especially in light air. By engine, it lost some bite forward most noticable in heavier seas. Good reverse and the prop walk which was significant on the fix prop dissappeared. I got a line in the prop which pulled the engine out of alignment but with no dammage to the prop.

I would buy it again, price and good enough being the two main reasons.

Kiwi or other feathering propeller

Since it has been a year since the last posting, I'm curious to know if anyone has updated experience with any of their feathering props - positive or negative?
How do the Kiwi props hold up over time?
Are there comments from owners of other brands?
Are you satisfied with their ability to maneuver in tight marinas - is it significantly better than your fixed blade props if that is what you changed out?

Thanks much!!

sailingdog I use a composite prop on my boat, that is made of materials similiar to what the Kiwi prop is made of and the blades are designed to shear in an impact. This can save the transmission and lower drive unit from being damaged. The blades are easily replaced. I believe that the Kiwi prop is designed with the same idea in mind.

PearsonCommander We got one last year and so far are pleased. The performance in reverse is much better.

The poster above may not understand that the Kiwiprop is intneded to have its blades replaced if the hit something...tht may be the reason he felt it seemed "fragile..."
