I have 3 Johnson outboard motors. Need to find out the gas/oil mixture ratio. Thanks for the help. Here's the info:
1) 1977 35HP Model 35RL77H
2) 1983 35HP Model J35RLCTS
3) 1990 30HP Model J30RLESS |

How about the oil ratio for a 1973 135 hp motor? |

All Johnson and Evinrude outboards use 50:1 since 1964 (including those supplied in the 1980s as using 100:1)
See http://www.evinrude.com/en-US/About.Us/FAQ/Oil.Fuel.htm#Q1 |

See the link I gave above for the fuel mix.
J4C plugs gapped at 0.030" but go to J6C if fouling is a problem ('52- '58 used J6C and an oilier mix!) |

"A ratio of 50:1"
But not for a 1959 model. 24:1 according to the link. That's 1 pint in 3 gallons. |

I'm curious why the 100/1 motors have been switched to 50/1? I have an 88 25hp and the factory lit. all said 100. Now it's 50?? why? |

Many powerheads blew due to that mixture. Obvious to many of us that a OMC goof took place. Need I say more? |

www.outboardbooks.com ... Even though these are for buying a manual if you know your model number you can search it and find the year of your engine. |
