Hard scale on Prop...What causes this?

[prozach]

At Havasu last weekend a hard scale formed on my prop. I have run the same prop several trips and it alway comes out of the water clean. What causes this...slippage? It is a bitch to get off.

Try Using Lime Away

[atomickitn]

we use c.l.r. it works , you have to scrub it with a brush them it wil be shinny again :D

Try Using Lime Away
yup!!!

Nothing works better than muriatic acid. Use some gloves and a mask though.

yea.. just throw a little alluminium foil in the bottle before you use it.. :D

Dont do that!!

High calcium deposits.......
KaBoom cleaner works good too.

toilet bowl kleaner works w/o scrubing, but u need gloves to apply

When your prop is turning in the water it is actually creating electric current similiar to your alternator. You are seeing the electoplating of calcium attracting to that current.

That's a great explanation.

I have also heard that a little build up will actually help the prop bite better. Clean, shiney props slip without pushing as hard on the water..... :notam:

I knew there had to be a technical reason for it. Thanks

Don't clean it. The slip factor drops dramaticly when it is all scaled up. Why do you think lab props aren't polished. Let them be ugly.

What he said! I read an article about this somewhere and the advice was the same. Thats why my boat is so damn fast :wink: NSF

Should I clean it or not??

Isnt that what I posted??? :confused:

Check the fuse for the Mercathode. (sp?)

[SnakeWrench]

NO, DON"T CLEAN IT!!!!! You could check the fuse in the Mercathode if you want, but it won't be the reason for the scaling.

If other currents are allowed to get into this bonding circuit they can easily overpower the small voltage available from your zincs and defeat the protection you need. This is usually the most destructive form of electrolysis and you notice it because your zincs get eaten up very quickly trying to keep up. Under normal circumstances, zincs should last at least a year if they are working normally, and much longer if you don't have any problems. If they are being "sacrificed" in a shorter period you need to find where the external current is getting in.

This stuff is getting deep :supp:
