Also,

Hardcoat anodizing will alter the part dimensionally. A build up of .002" on 6061 T6 alum is not uncommon. Therefore, a bore diameter could be as much as .004" smaller after anodizing. There is a masking procedure to eliminate coating unwanted areas.

Because hardcoating is an electrolytic process, sharp edges can have a greater buildup due to increased current density. This is of special concern when threaded parts are coated. Electroless nickel plating offers excellent corrosion resistance and lubricity for aluminum parts subject to wear. There's a post heat treatment that can significantly harden the high phosphor nickel plating as well.

Fred, if you look at the front of my motors, everything that's purple is Anodized not powder coated. I'm powder coating all of the diamond plate for the bilge, all mounts, rails and acc. mounts and the alternators but the whole pulley system is going to be anodized along with the sea pump (if possible to change the color).

no ,you needed to have the hardcoat done first. the hardcoat process will not be effective with other metals present ,big no no. the paint is ppg dp epoxey primer followed with ppg concept sinlge stage urethane with d 897 hardner. very durable. you can spray wet on wet. the only draw back to using the d 897 hardner is that it takes 48 - 72 hours to fully dry to the touch. but when it's cured ,it's tough as concrete. you will lose some of the high gloss luster about 15% using the d 897 . i did my power in med gray. going with pearls and bc / cc is a waste of money. once you have all of your runnig parts , it's mostly covered up. by doing it in a lighter color it will look alot more appealing ,especially with the red and blue jewelry :cool: :D :eek: :D :D

you can always go cloosed cooling , that is the best route to go (imo). i'm sure TRICK marine can bling you up :D :cool:

Open, Humor me for a second since I know you have been there, :D

Say I have the guides and seats taken out, What is the approximate cost to Hard anodize? Is Canfield the place? I can't be the first guy to decide to go this rout at this point.

I know closed cooling would be the answer but all that plumbing and it is so, so , so dang unattractive.

Re: What is the process of hard anodizing?
 

you want humor , let me get jc perf on the line :D :D :evilb:

the cost , i would not know. i would have gone cc myself ,but all that eickert jewelry is to purdy not to use. :D :D look n your local phone book , unde plating and anodizing , there s a company here that does it , the start fee is 300.00 (min they will set up the tank)

gottsa yellow page book ??

[QUOTE=Breathe Later]Also,

Could you limit to just the external surface and the water jacket?

If so, would it be OK to leave the guides and seats in place?
