The centrifuge force created by the rotation wasn't enough for the propeller to overcome the force of the water flow. The solutions could be either increasing the engine RPM or reduce the props pitch. That simple!

I still get some comments and DM's on these FlexoFold video's. I took the propeller to a local workshop who fixes bent propellers and such, they found that there where an imperfection in the propeller that made it vibrate (Weight difference in the blades), and that again made it collapse when it had to rely on the centrifugal force to hold it open in reverse. The issue was fixed and the propeller performed great after that. Although FlexoFold did get back to me, they used all their e-mails and a phone call yelling at me for makin a bad video about their propeller than actually helping me and giving me tips to find the problem. Hope this answers your questions. 🙂

As far as I can understand by the video, your propeller is Right but your engine is actually Left (or the opposite anyway). Nothing to do with the size or the weight of the blade.

I have had 3 flexofolds on 2 different boats, Amazing props. You sir, had the wrong prop size on the boat. The italian job you switched it for looks smaller and heavier.

I think I saw you

Flexofold is a nightmare to work with. They sent me the wrong prop then refused to replace it. No one would install it for me when I told them it was a Flexofold prop.

Tack för att du har delat den video! Det är dags för mig att köpa ny propeller.Efter har pratat med fler återförsäljare alla säger att Flexofold ser ut modernt men i visa fall kollapsar vid revers. Varifold och Gori blev det!

I use the Zinc spray! Petit Prop Coat. Two thin layers. I remove it every year with glass beads in a blast cabinet and put another coat on. Its only about $20.00 per can and the can will last two seasons.

Hi I have the same problem with Flexifold 3 blade, has been tested and there is no reason why it won’t open. Have you found a solution?

I know this is old video. I was Googling for this prop brand reviews and came here. I just bought my boat with this prop and was curious....Anyway, I have no experience with THIS prop but looking at your other two videos I suspect that your rudder is very close to the propeller to generate the needed water flow for it to stay open. I would love to know if you found a better solution since this video.

I have the exact same problem with the same prop.

Did you hear anything/ know what the problem is?

Any one notice the clever edit? Our Vlogger missed putting the circlip on the bearing end of the shaft, it was on the paper at one point & then "hey presto" it wasn't! However this was very useful as I'm doing the same replacement at the moment and needed to confirm a few things (which was how I knew he'd gone wrong!)

I have a three blade Flexifold and it has never failed since I bought my 50' Beneteau in 2009. It has always worked flawlessly. I have both called Flexafold and Emailed them for advice on a good coating to reduce barnacles and they have always responded!

What was the pitch?

:)

😊😊😊👍👍👍

In May I purchased a 2-blade flex-o-fold, placed it on the boat, boat was splashed and upon placing boat into reverse to exit the lift slift I could feel an unusual vibration, went into forward and vibration was worse and at 2000 rpm my vision vibrated, that's not exaggerated. Pulled boat 2 more times, one to reseat new prop, the other to put old prop back on. Needless to say I'm very disapointed so far. I emailed them and called to leave a message, hopefully I hear back from them. Too bad too because the boat moved nicely forward and reverse with no reverse prop-walk.

Hi ! Very nice video. What do you think about your Mamba 311 having a spade rudder? Would it be worse for offshore cruising than a skeg rudder? I know this has been discussed quite a lot before, but I'm not sure about what to look for in my future boat.

put a real prop on it

gonna say must be a gay sailboat with a gay looking prop like that!!

Is the new (Eliche Radice ) prop still performs well? any advice on this as I'm just about to purchase on. Cheers

you are making your life hard - get a weight belt - get neutrally buoyant - get some fins on (civy flippers) you might even try an SSBA - surface supply - our flexofold is nothing short of brilliant - so not sure what has happened in your case

My Flexofold works perfectly, once I learned how to use it. The last propulsion must be forward, over 3 knots to get it to close while sailing. In reverse, there is a click sound, actually locking the blades into place at low speed, then once in reverse, backs beautifully. Almost more reverse thrust than my old fixed blade prop. It is all about allowing the shaft to come to a stop, I think, before going into reverse. Beneteau Oceanis 351.

Did you ever hear back. Currently looking at one of these and want to know wether to steer clear. Thanks for the video

Hi, Love the honest feel of the video... thanks, about to buy a sailboat that has the same engine and is in need of the same repair...

I have the exact same issue with my two blade Flexofold propeller! Please let me know if you found a solution.

Ok, now we've seen it all. A Maxi 77 breaking ice.... ;D

How much did you paid for the cockpit-hood?

Surely there cannot be that many people in Norway? Someone must know these thieves ? Anyway Happy Christmas.

It's always disheartening finding all the new problems with an old boat, and that's a big big project, but after all the work you'll have a big spacious family boat, so the effort is a good investment. I've wasted lots of time/effort in the past trying to "repair" interiors, and have come to the conclusion it's usually quicker and cheaper to pull everything out and start with an empty space (just as you're doing) The destruction is quick and finds all the problems at once and then the rebuilding process feels much better. It will be really interesting to see how you refit the boat ... especially for the cool Scandinavian climate.

Breaking ice with a fiberglass hull is a very bad idea!

Shit. Merry christmas, anyway.

what kind of boat?

oh no! that sucks!

What's the make and model of the new boat?

good to see an update :) i had been wondering where you had gone lately. sorry about the gopro issues, but good luck on the continued boat rebuild. i look forward to seeing your progress. hope to meet you on the water some day.

Propane torch, Easy-Flo low temperature brazing rods and thick brass or bronze sheet to be shaped and brazed to the rear of the blades. (try to get the balance correct) The object of the exercise is to make the blades heavier in order to generate more centrifugal force. Plumbers soft solder could be used for prototyping as its much easier to undo if plans change. Thin light blades are useless if the propeller needs centrifugal force to hold it open in reverse.

Don't be too discouraged. I too know the feeling of fixing all the poor repairs from the previous owner, as well as new damage from neglect. Check out my videos if you want to see real scary rot.

I enjoy the updates! it will be impressive to see you rebuild it.

Ser ut som om du har en enorm jobb foran deg ja. Har familie ikke så langt unna nøtterø. Fantastisk fin plass. Er målet i fremtiden å bo i båten?

Wouw, you got alot of working to do. Wish you luck and fair winds

Good luck with the project! It looks way better than my project boat! If you want to see a scary project, check out my last video.

Wow that is a definite change. Your title wasn't kidding! I hope it all comes together smoothly for you. Good luck and look forward to seeing the next project come along.

This is a really nice video. Sorry to see your sailboat is on hold for a while. Good luck with your motor boat.

Good luck with the new project... hope you get out on the water again soon, It's really interesting seeing videos of your Norwegian cruising ground.
