    Need help with 1968 1.5 HP Johnson model SC-10S

    My wife says that I am old stubborn nutcase... I am not a mechanic , but I was able to revive motors that are "spaceships" comparing to this motor that is simple like a rock. I will not be in peace with myself if I give up now...

    Need help with 1968 1.5 HP Johnson model SC-10S

    Compression is 110 on cold engine. Motor came with canoe I bought locally. Considering its good condition, extreme simplicity and parts availability I expected it to be as easy as a "sneeze" to fix it. I do have experience with OMC motors from 6 to 85 HP. I had similar issue this summer fixing...

    Starter goes on on running engine, 1979 85HP Johnson

    Hi, I have 85 HP 1979 Johnson (85ML79R). I noticed that when accidentally turned key to START position while engine was running that starter went on crashing bendix teeth. I thought that starter is supposed to be blocked from running while engine is running. Am I wrong or something is not right...

    Need advise on Manual Tilt Assist Shock Absorber installation for 1970 85 HP Johnson

    Thanks for the link. I do have OMC manual for 1978 model which is basically the same. It only describes power trim and tilt. Also, I got PDF manual for wide range of models that only mentions manual tilt and recommends not to take it off because it is "difficult to put it back". I do have the...

    First Tohatsu motor 9.9HP

    yes, trigger coil was the problem. All other parts are working. I will try what you said tomorrow, but I am not sure how to correctly adjust the linkage from cam follower to throttle. Is it what MattFL said? Can you confirm? On all OMC motors there is a mark on a cam for that. I can not find...
