powder coat a prop

[jake0]

Can a SS prop be powder coated? will/can it burn off if the prop has cavitation due to running the motor a tad high ( in tight turns)

[Mad-One]

Can't See why it wouldn't be able to be powder coated

[warrior]

they would have to etch it first i would imagine then powder coat,polished is definatly better for performance imo

[Matt76]

Yeah would have to be etched and definately wouldnt burn off, It would only wear much like paint does.

[Lachie1]

What do you intend to get out of powder coating it?

[oldboot]

why would you powder coat a stanless prop???.

Serioulsy why?:-?

Polished stanless would have one the lowest possible coefficients of drag.

A stanless prop will have very finely shaped entry and exit edges.....powder coat will ruin that.

Guaranteed....some time you will scrag or at least wear the coating......retouching powder coat properly is impossible..so ya have to stripp it all of and redo.

I would not even powder coat an aluminium prop.....Id go an etch primeer undercoat and then a conventional wet topcoat.......at least that you con retouch.

Besides.....unless the prop in question is an all metal item with a removable bush....tha baking process will buger up the rubber.

Just pure looks, I did see a few props done like this on go fast US boats, they looked very smart, they had Verados on the bum and looked like black chrome props, i quite liked it

Were they powder coated or ceramic coated?

[Lachie1]

I don't think the fish will mind bud, polished stainless looks pretty good when its parked up in the shed at home anyway:P

[oldboot]

I can see real reasons for either creamic, teflon, graphite coating a prop.

All may improve performance and possibly durability.

Standard powder coat aint going to look like black chrome


If ya worried about what your prop looks like out of the water.....hell you got too much money and the prop spends too little time in the water.

cheers

[Roughasguts]

Mate get a nice S/S prop black chrome it and have gold leaf lettering on it if you like, But use it for show only!! Never let it see the water cause it will be ugly in minutes.

He He wish I had so much to worry about.

No...not worried on what the prop looks like, Im getting it done so i know how it would look,(shit hot) most boats that i know of spends more time out of the water than in. heck....cant spend the money when your dead....or can ya:o.....maybe not;D again "I" like the look of it;D


Others that posted, thanks for feed back, i have miss lead myself, its not powder coat, its 'Black chromium' and has a couple of different looks. unsure of who does this in Australia as yet, but by the end of the day im sure that WWW will help me
I think a "White Chrome" prop would look shit hot on a E-Tec8-)

[Roughasguts]

I had factory black chrome exhausts with gold lettering on me old GPZ Kawasaki It looked great for 6 weeks then started to go milky and that was basically the end of the good looks.

Cheers.

[jake0]

Thanks Roughasguts, The heat from the exhaust would of made them go milky? you think it would do the same with a prop?

[thylacene]

Powder coat wouldn't be all that practical, it is effectively a plastic coating and would adversely impact the performance of your prop, dulling the leading edge and changing the flow over the vanes.

Your best bet would be to have a chat with your local electroplater. I bought a set of black chrome MAC tools here a while back. They are gorgeous.

There was a blurb on the box about the process, it involves multiple plating layers, copper, nickel, black chrome and chrome as I recall. Chrome is actually clear, it is the layer of polished nickel underneath it that gives the silver effect.

Would look way flash!

[bigdonk]

I just bought a New Yamaha 4 stroke and it has a black powder coated SS prop on it... can't be all bad, if there is a performance difference between the polished and painted..... Maybe half a Kph faster at 6000rpm.. so small you could't tell the difference!!!

I honestly don't know It could have been the heat, or Adelaides crappy water, or just the quality of the black chrome from Kawasaki.

It still looked okay but it would have been nice to restore the finish maybe there is some purpose polish out there now for it.

Cheers.

Here's my process :

1. Ultrasonic soak clean
- UDYPRxx 110 = 55~65 g/l
- Temp = 60 ~ 70'c
- Duration = 5 min

2. Normal soak clean
- UDYPRxx 110 = 55~65 g/l
- Temp = 60 ~ 70'c
- Duration = 5 min

3. Cathodic clean
- A-CLxxN = 10~15
- Sulfuric ACID = 10~12%
- Temp = Room temp
Duration = 30 sec

4. Acid dip
- HCL Acid = 10~12%
- Temp = Room Temp
- Duration = 30 sec

5. Nickel Strike
- Ni Chloride = 200~220 g/l
- HCL Acid = 60~90 g/l
- Voltage = 3~5v
- Temp = Room Temp
- Duration = 45 sec

6. Activation
- Chromic Acid = 3gm/l
- Duration = 20 sec

7. Black Chrome
- Chromic Acid = 400~430 gm/l
- B400 = 25~35 gm/l
- Voltage = 5~8v
- Temp = 18~24'c
- Duration = 7 min

8. Hot water rinsing
- Temp = 70~80'c
- Duration = 5 sec

* there are 2~3 water rinsings after each process

I hope this should help

[oldboot]

Yerh and the first time ya get a bit close to a sand bank it will look like a piece of rubbish.

I thaught a stanless prop was some sort of status symbol on its own.........at least if you scratch up a plain stanless prop it is an easy job to polish it up.

cheers

Well I supose the fancy boys will have to change to titanium...you can do some fancy tricks with that.

once you polish it up....by heating it you can get it to change to a variety of fancy colours..lovely pinks, blues and purples.

Get sick of the colour, just heat it up again and try your luck with the colours.::)

cheers

Nope...........Chrome Black will do me just fine for a while;D;D;D::)

Plus i can sit in the shed where the boat sits most of the time::) and admire the new look of the prop,cant do it while its in the water;D;D when i get sick of that prop i will go out and buy another SS prop and look at that for a while, do you see where im getting at???::)::)

[DOGFIGHT]

Mate i think you may be on to something with this color match props, the black chrome would look nice on a merc.

No,not really,I'm too bloody busy filleting these fish to admire the prop,although it's a dull alloy one.
