Any such thing as a conductive oil ?
 
Looking for a conductive hydraulic or ATF oil . Is there any such thing ?

Hightower 17 April 2010 17:01

What as in "electrical" conductive?

ATF is transmission oil or a version of hydraulic oil ... what do you mean by 'conductive' ?

all oils conduct heat, only conductive oils i heared of are for model train bruches.

Why ?

Conductive as in electrical . My tilt rams are sitting in ATF oil and are not being earthed because of the oil and rubber O-rings therefore they are being pitted because of electrolysis . If i can find the right oil it means the rams are earthed because of the bonding on the engine and clamp bracket . All anodes are working properly with the bonding circuit but because of no earth on tilt rams the stainless is pitting

Are you leaving your engine tilted up?

Yes , always , but passing boats create a wash which means my leg with a stainless prop is bobbing up and down in the water . Stainless , aluminium , and metals ! I'm being told is a bad mixture and the fact all is earthed except tilt rams which are sitting in oil and sleeved in rubber O-Rings means they are sitting ducks . If i could earth rams then anodes would take all stray current

Why not leave your engine down so the anodes can do their job? The rams will be touching the engine then.

surely its easier to fit a small earth strap across the eyes of the ram to ground? to bypass the rubber bushes?

I suspect it's the trim rams that are the problem-with the engine tilted up there's no electrical contact to them so they won't get any protection from the anode.
