Thanks for the tips and info Dave...you clearly know a lot more about this than I do!
You are right, everything is plastic. As far as I understand it, no matter what I end up doing, I need to get the backing nut off, get the wet rotten plywood off, and get the sender out. Yes, I concur that I would like to start with clean fresh surfaces. My confusion is when you refer to a through hull fitting and the sender separately. I had thought that the sending unit was essentially the through hull fitting. My understanding of the process is: once I get the backing nut off and all of the plywood backing plate off, I would next need to go under the boat and slide some wire underneath the mushroom head fitting to cut any sealant. Then I need to go back inside and grip the sending unit (where it is not threaded) and try and rotate it to break it free of sealant. Then I would clean everything, make a new backing plate, and remount. Is all of this correct? Of course, if this doesn't work and I can't break things free without destroying them, then I suppose I just need to do whatever it takes to get everything out. Then buy a new sender with hopefully the same diameter. Again, is this correct? Thanks again, Mike Sent wirelessly from my BlackBerry device on the Bell network.
