CONTINUOUSWAVE

Hello. I've read a lot of great info on here about the oil injection bypass on the older mercury engines. I just bought [1998 Boston Whaler DAUNTLESS] with a 1998 Mercury 135 offshore engine. We bought it from a woman who recently lost her husband. She was able to tell us about the bypass but wasn't sure on the ratio. I couldn't find a specific answer to the ratio for a 135. I assume it's the same 50:1 that everyone is talking about but was curious if someone could confirm this. Thanks for the help--Todd

The gasoline-oil ratio is mentioned in the article in the REFERENCE section at

The original oil mixing system aimed for 50:1 at full throttle. If the mixer has been disabled and pre-mixing is used instead, the mix ratio would have to be 50:1 if you ever ran at fill throttle.
