Just bought a used boat with a 60hp Johnson on it(1988 model). There's a separate reservoir for oil so mixing oil/gas is not necessary. However, the guy I got the boat from warned me that the oil pumps are notorious for going out and that I wouldn't know it wasn't working until the engine blew up. So he mixed 50:1 in the gas AND put oil in the oil reservoir. What are yalls thoughts on this? Isn't it too much oil? What if I just always mixed 50:1 and said to heck with the oil reservoir? Is that a bad idea? If I just went with mixing my own, what do I do with the oil reservoir? Thanks ahead of time...
