About to dig in to installing a heater on my ‘92 Prostar 190. I think this is the spot to mount the core—lag bolt into these? Based on the spacing I think I’ll need to attach a treated board to the boat and then mount the heater to the board, as I’m in installing a three vent heater and it’s wider than these two mounting points. Looking to confirm with others who have the same era boat before I move forward—bonus point if you have a picture!
