I have a 1971 Johnson 20 hp that I am replacing the lower unit seals. I did a pressure test on the lower unit and it was leaking from the shift rod bushing/o-ring.<br /><br />I have the Factory Service Manual & the Selco shop manual.<br /><br />I purchased the Sierra seal kit #18-2684<br /><br...
I am looking at a Johnson 28 hp and I was hoping someone could determine the year for me.<br /><br />Model #: R x L - 12M <br /><br />Serial #: J2483111<br /><br />Thanks!
I have an electric start 1971 Johnson 20hp that is backfiring (single loud pop).<br /><br />When I turn the ignition the motor will crank and then backfire once. After the backfire, I turn the ignition and she fires right up and runs like a champ. <br /><br />It only backfires once before it...
