Author	Topic:   GROUND FOR INTERNAL GAS TANK
Bear	posted 04-14-2003 12:57 PM ET (US)         I'm in the final stages of putting the gas tank back in my 88 20' Outrage and am replacing the ground that goes from the aft part of the tank to a bronze/brass circular disk mounted on the stern below the waterline. I need to replace the circular disk.....anybody have any idea where I may be able to find a replacement??? Thanks...

JOHN W MAYO	posted 04-14-2003 01:48 PM ET (US)             That circular disk you are talking about, I have one on my transom, below the water line, right side. I have never know what it was for, is that the disk you are saying is a grounding disk?
mustang7nh	posted 04-14-2003 03:43 PM ET (US)             I have an 88 also 20OR. When I took of the speedo and fishfinder that didn't work from teh guy I bought it from, I assumed this was some sort of transducer. I ripped it off and cut the wire where it passed through the transom. Is this a safety hazard?
Bear	posted 04-14-2003 03:47 PM ET (US)             Yep...closest I can deduct from previous threads on this site, as well as what I've found from essentially taking my whole whaler apart, is the ground path is green wire from fill on port side to attachment point where fill enters the tank. From there is goes through skin of tank to next green wire attachment points at circular plate where the fuel hoses attach. Green wire goes from there to circular disk under water line. After 15 yrs, disk is toast, needs replacing.
