Great work. All great stuff was always made with a craftsman, hammer, anvil, heat, patience and a commitment for perfection.

Enjoyed this immensely. Precision, tradition, human touch. To spec, in spec, cleanliness every step.

Love the music ! Totally complimented the video.

What a process, had no idea. Very cool to see each step. Nice video Yamaha!

Yes, "A little less Cowbell please"...... But if you're serious about learning, there's a lot of incredible detailed information in this video for anyone who has done a quick study in the "lost wax process." Do that, then come back here and see the "specific mold process" for their props. And the comment about "...large man and a mallet...", paraphrasing, that's exactly what you'll see in a foundry operation, prior to any machine-finishing. You have to "get close" before you can be plus or minus a few thousandths. To straighten our cast bronze plaques, we slam them onto a cement floor or metal table. It's not pretty, scares everyone not wearing hearing protection, but then, that's how it's done. Actually a very good video...... thanks' Yamaha YPPI

Nice explanation of the evaporative pattern process. I think that they occasionally confuse the term die and mold but all in all it’s a nice piece and helps customers understand why that shiny new prop is so expensive.

Very well presented 10 out of 10

Cool Presentation. Good Workmanship

Never been aware of this process, and I’ve worked in the trade for decades. Thanks for sharing. Really interesting! 😎🏖🌴☀️🇦🇺

Love the music! Thank you.

the foundry process was more efficient than i expected

I liked this. Thanks!

They are great props the problem is the sws2 sds has been a nightmare back order for almost a year only to slowly trickle in.

Why is there a Jet-li fighting theme on the foreground? "Ya kickin ass while ya mekin propz brv"?

Thanks to Yamaha for my F80BETL. The best outboard in the world!!!!!

Too much music.

I love to hear the sound of manufacturing. But it's a nice vid!

Really amazing to watch,thanks,just better if you killed the background noise.

I love how the final inspection process shows a large man smashing the prop with a mallet.

Great video

30-012023.Do you recyle any used shell matterale???No cobalt on the frist coat?No laser check or controle on end product??

Props to you Yamaha.

Nice video thanks !

After we spend hours grinding,polishing,measuring,we beat it with a hammer. Who produced this video? Was proof of quality production your goal???

It's a heavy metal concert not an info video.

3:38 great way to seal a sandblaster box. how does that guy see through all that painter's tape?

Lorddd I'm Exhausted. Just by seeing the Process

It's 2018. Could you not steamline the process so I can buy a standard propeller for a F40 for

MUSIC IS UNNECSSARY !

Yeah the sound guy went bonkers with this music. Geeeze dude we're you working out during editing.

I had to stop the video to check if the music isnt playing on the different opened site.

5:10 ah yes. hammer it right into spec to yamaha standards.

Wow PROPS to whoever made this video

What’s the music they used it’s fire

Remove the music! You can barely hear what they're saying.

What is the song?

Do you balance the props?

They got me for 20 seconds their obnoxious noise had me get the hell out!

Lots of good information, interesting to see investment casting done on an industrial scale. I know a lot of people that don't work in the industry will be shocked seeing a guy with a hammer, but that is a highly skilled job and that kind of hand work is why they are able to make them with casting rather than expensive 5 axis cnc. If they didn't have that guy, those props would look good, but not proform nearly as well. A skilled guy can tune the prop for specific applications.

♥.♥ I really like the Lost Wax method for casting: wax pattern→ceramic slurry coating→silica sand or zirconium coating→drying→dewaxing(by heating)→pouring molten metal.

Hard to understand because of the awfull noisy background sound.

Very interesting video. Makes you appreciate why they are so expensive. Lower the music volume by 50%

What city is

music is essential part .. ultimately it is originally sound company.. look at logo....

I just ordered my Talon SS prop ;)

A propeller is a complex device whose complexity in the surrounding working medium is hardly respected hy many people. If the propeller accelerated very quickly then the medium around it cannot cope and it is left behind to cause cavitation, At speed the forward speed acts as a primary pump to the high pressure areas and so the blades can cope with higher pressure differences. I prefer propellers where the pitch at the hub is slightly less than the pitch at the outer radius of the blade, This is due to the fact that at slow speed the angle of attack of the blade with respect to the water is so high and at that zone the blade acts more like a paddle wheel rather than an airfoil section. Also it would bite a bit better at slower takeoff speed. Normally I arrange for the inner hub pitch to be just right for normal cruising where the inner part of the blade is not working but simply going through the fluid without drag, but it would be working at slower speeds and it would behave better when the craft is moving slower . There is so much complexity going on around those blades, where many people misunderstand the difference between cavitation and aeration . Also I find that the tips of the blades are important for efficiency, IN the older days the blades where shaped more like clover leaves with the trailing edge raking in . In a propeller and an aircraft wing , I prefer the outer tips to have both the leading edge and the trailing edge raking back. When young I did notice that very bird and every fish have their fins with the leading and trailing edge raking back. When one comes to think of it the pressure differences around the tips would mean that if the fluid is trying to escape from the high pressure zone to the lower one, then it would be logical to move the "wing, blade outwards so to stop the fluid escaping. Nature had done it all before and evolution of birds and fish.............. has done it all before us............ and one can appreciate why high speed propellers look like the wings of a diving eagle or a hawk and looking at the tail of a whale , an Orca and a dolphin one can see how much there is to learn from the shape of their wing tips and fin tips. It has been there for a million years and it is such a pity that many people did not notice it and ventured to design their own............ not getting it so perfect as nature did.

Jose finishes it off with a mallet?

Good video but the music is too loud and drounds out most of the dialog.

Interesting process. I curious if the props need to be balanced and if yes than how is that done?

Yamaha is the best at everything they fabricate.

How long until this is replaced with 3d printing? Saw Blue Origins printing titanium alloy rocket jets the other day. Amazing

Im from Indonesia,like Yamaha 60hp?

Donde están los modelos de propelles Para evinrude etec

Sorry I must have missed something but is my propeller made of aluminium coated wax?!

Respect !👀👍👍👍

Super

Can you do one without the music guys, as others have said really distracting

I like the music. Keeps the whole thing moving. Great piece.

Music is way too loud.

Namber one yamaha

A boat without a prop is an island, that's what I tell my customers.

A mold could be built that would produce one piece finished wax props, it would surely save you money over building them piecemeal over the long run.

Yamaha 😎

Hacen propelles solo para yamaha turbo hacia para todos los Outboards

Please turn up the music, i could almost hear what they were saying.

tay nghề giỏi quá .

Woah, way more complicated than I thought. Thought they were my old recycled Pepsi Cans.

background noise is way too loud to hear what your sayin'

the music could be a bit LOUDER

Not quite sure why they keep calling the wax mold process a wax die. Molding is injecting a liquid material into a hollow cavity. A die is a forming process with a solid material.

no balancing of the propeller ?

1:00 melted out the ceramic?? Pretty sure they melted out the wax.

Burns is a good dude. While I was at Yamaha, it was widely acknowledged, that Mercury builds a better prop than Yamaha.

Turn off the lame loud music and then professionally explain how this prop on my vessel is made, I didn't come close to watching the entire video

Whats the difference between a flour and a powder? thanks a million.

Now I know that whenever I buy a prop from Yamaha, it will be beaten hard by a sledgehammer before they send it

Tried to watch it, but couldn't because of the music.

Hit it with a big hammer to get it into shape standards, awesome

Great music, makes it very exciting!

Did he say they melted out the ceramic?

Why do you not have guards on the presses?

Very nice😚🥰😅😊

…lost wax process, another example of ancient innovation. Most people these days literally believe that these kind of components cannot be made without CNC or 3d printing.

Mercury hace para todas las marcas de Motores

Info A+, Music D-

Nothing says precision like a big guy whacking the propeller with a massive hammer!

will 3D printing help?

Agreed the music is just to much for the video . It tends to drown out the information in the video . Not that I'm even going to try to learn how to make a prop from this video . But never the less still think it's a good educational video and would like to see more like it but with music that's not so over powering .

Surprised they aren't CNC machined nowadays. Seems like a long labor intensive process for a simple object

no mention of balance

Intresting video! buut skip the music,,please,,

also known as the lost wax process.

QC.. “hits prop with hammer repeatedly”

Elice para suzuki 50 mod 89

Mercury can show you the best way to make a prop

Wellding props

man discover wheel, man make propeller with like 17 different steps!

Who in North America is listening to this 80's heavy metal cruising on a boat??? It's 2019 not 1918!

OMG this music. Go to any meeting or presentation by a speaker, Do they play music while presenting/teaching/speaking. Does the CEO play music during his board meetings. NO

and this is why props are expensive
