Our Fire Department recently purchased a tritoon with an '87 150hp Black Max. The previous owners were concerned about the oil injection failing, so they had it eliminated, and started premixing. The previous owner kept telling me to mix the fuel, 50/50, which I know is wrong. I am assuming he meant 50:1. But I am asking just to make sure. what is the proper mixture for an '87 150hp Black Max?

You got it right, BLS. 50:1 is the right mix.
