Got a new anode for the heat exchanger for my VP engine & outdrive.
It's NPT so normally Teflon tape to make sure no leaks but I don't think you want to have any insulation between the threaded female NPT opening and the anode. But maybe once installed, the threads cut up the Teflon tape and make a solid electrical connection.
Old anode (unknown time in use) was totally shot and looks like it was installed with Teflon tape.
Others with closed cooling must have been through this.
