Hi all,
I have a 1979 35hp Johnson outboard. I took my boat out today and the motor jerks about every 10 secs. It jerks more at faster speeds. I think it is the clutch. I ran it in reverse and it still jerks. It ran fine a week ago. Three days ago I adjusted the Spark plugs gap to 0.030. Could this play a role in the jerking? Maybe the linkage is adjusted wrong? It jerked before a year ago but it went away.
I have changed the clutch and seals on my 1979 4hp Seaking motor and It wasn't too bad. The only difference is that the Johnson has a reverse gear. How hard is it to change the clutch and seals? I already have the seal kit for it and the service manual. I don't want to crack the lower unit open if the problem is something else. Thanks inadvance.
