Favorite penetrating oil that DOESN'T STINK!

I tried to hire a diesel mechanic for the first time in 12 years of old boat ownership. He didn't seem excited to do the job and told me to apply penetrating oil to the rusty prop-shaft coupler several times and then maybe he'd come back and do the work.

Hmmmm..... if it was easy, I would have done it myself.

I've never been a penetrating oil kind of guy. I prefer the "heat beat and repeat" method. But I took his suggestion and bought some Kroll oil and applied it in copious quantities.Several days later, as I was approaching the boat, I noticed a strong "simple green-like" smell. It was the Kroll oil! My entire boat stinks now, and I can smell it from the dock.

Needless to say the kroll oil will not be used again. What about PB-blaster or "break-free"? Any other favorites that don't get you high like brake cleaner does, or smell so strongly that it overpowers the usual eu-du-boat?


I have a sauna on my boat, therefore I win.
