I'm trying to learn a little about the engines on my new boat. I have taken a few pictures of a fitting on my boat's 135 hp Ford engines (1987). I have no idea what it is. It is on the front of the engine near what I assume is the fresh water pump. I notice that when I turn the nut on the cap fitting, the bolt turns as well. What's up with that? Should I be alarmed? Should I ask for a refund? Nothing is leaking from the fitting, but I'm still curious.
