I picked up the component spray at Radio Shack and the heater worked perfectly. I have a single screw 350 Merc. This year will be my 1st, in the water through the winter. I’m in Washington State so freezing isn’t a huge issue, but still a factor. I’ve attached a couple of pictures to show you the placement of the heater. Does it look OK to you? Thanks again for the help.
