1976 Johnson 115. I'd like to change impeller on water pump and notice that there is red RTV at the mating surface of the Lower Unit and motor. Is this supposed to be there? I don't see any sealer being used when I watch other LU repairs on Youtube. If it is not supposed to be there, any thoughts on: 1) How to seperate? (I'm imagining this will make disassembly much harder) 2) Good way to remove RTV and 3) Any suggestions to clean up mating surfaces?
Thanks in advance
