Checked on the boat today for the first time in 7 or so weeks since winterizing. I noticed this past season I was having to put a little antifreeze in the starboard engine after a couple runs. I noticed some coolant in the bills today, and traced it down to this bolt on this coolant tube. What is this about for, just a drain I'm assuming?

yea, just a drain. Dry it all up and make sure it’s actually coming from there though. We had a leaking J hose that was slowly running down to that point and could’ve easily been mistaken for a leaking drain plug, since it’s the lowest point it all runs to there
