fuel mix question?

[adominique0313]

Hello Again,
I have two motors (main and kicker)
1) 2002 Johnson 90hp j90plstc
2) 2006 Johnson 15hp J15rsdr

Can anyone please help me with what the fuel mix ratio is for both of these motors?
ps. I want to run both motors from the onboard fuel tank. The 90Hp has direct inject ( I am going to have it removed and mix in my tank). Then I am buying a fuel separator so I can run both motors from one tank. Unless you have any other ideas?

Thanks Again.

50:1 on both. Not the best idea to run on a single tank, though, if the 15 is also to be a get-me-home motor. That is, would probably be fine -- unless a fuel or tank related problem of some kind.

The oil injection on that 90HP motor is a good system. it is reliable, convenient and helps the motor to run better due to a fresh mix everytime. You might consider a separate tank with premix for the small motor.
