Hey guys, I just bought a boat that has a Chrysler 457hf outboard on it. I think the year is 1973. Problem is I dont know anything about this motor. I want to fuel it, but need the fuel to oil ratio. I also need a Air cleaner and housing for the Carb. It appears to be missing. Any help would be most appreciated. Thanks in Advance. :confused:

1 pint 2-stroke OB oil to 6 gal gas. 45Hp. No air cleaner. They are open-throated. No dirt to worry about on the water.

Thanks for the info WillyBWright, you are the man!! I thought that it might not have a air cleaner, but had to make sure. Is that Ratio like 50 to 1. Thanks again for all the help.

50 to 1 is correct. Also the year is correct for that model number. Your motor is 1973
