As dumb as you may think I am right now, I bet you by the end of the story you will realize you feel the same way. now, maybe I am just an odd duck, but since I was 16 racing around in old Road Runners, Souped up VW’s, Mach 1, all sorts of Mustangs and Camaro’s,
Firebird, Road Runner, Corvair’s, and yes even a 1955 Studebaker. I learned how to tell what was wrong with the car by smell. Transmission fluid leaking has a different smell than sweet antifreeze and oil burning. Even where its burning. Exhaust manifold smells from leaking valve cover gaskets are different than exhaust in the pipe and so on. Heck you can tell if an engine is running rich or lean by smell.
So while out on my boats, my nose is in full gear. Sniffing away, and because of the air flow design, you defiantly get a wif every now and then. The smell I am always on high alert is fuel smells. I have been able to tell that one of the fuel lines needed a bit of a tighten. Or that I have over filled the oil. So next time you are out on your classic boat, take a sniff while running, it wont look strange, tell them all the cool kids are doing it.
