I have installed a basic 40 isotemp water heater on my boat. I have started a project to clean and replace the anode/resistance heater. Does anyone have experience of how to remove the heater cover (8 screws) and the anode/resistance assembly? i bought the 55mm hex wrench but there is no room for it to turn! I removed the screws from the cover, but it won't come loose! Can someone help me please?
