Johnson 150 Jetting
I have a '99 150 Johnson. After 2 seasons
of headaches we found a loose fuel line union behind the gunwale leaking
air at idle. Now the motor runs strong.. so of COURSE I want to mess
with it. I have read that the 150 can be converted to a 175 by mere
jetting and timing changes. Is this true? What are the implications?
