powder coat a prop

[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!!!

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

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

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.

ROFPML, damn you roughasguts...........now have coffee on the keyboard

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
