Re: Merc prop 68-70 vintage

Well, I was just talking about turning the prop by hand. I have done it before so I know it can work on these little props. Anyway, the alternative method that these guys like is to take the prop off, take a Sharpie and make index marks on the inner hub and outer part of the prop. Put the prop back on and run the engine where the condition exists. Then, take the prop off and see if the index marks are still in alignment….or not. If not, the hub slipped.

Long live American manufacturing!
