    Acceptable Spark?

    1986 Evinrude 140<br /><br />Need a little clarification on what an acceptable spark looks like. In doing some trouble shooting I checked the spark on all four cylinders.<br /><br />Each had spark and could jump a 7/16th gap, however, the spark just appeared to be a thin blue line to my eye. No...

    1986 Evinrude 140<br /><br />Warning horn was dead (it shorted right at the horn due to exposed wire). Replaced with appropriate OEM horn. Now I get a constant tone everytime I turn the key to the on position. <br /><br />At first I thought maybe something was grounding out in the control...

    Warning horn on my '86 140 hp has "bit the dust" and needs replacing. Cost of an OEM replacement horn is about $50 US. <br /><br />Could you replace this horn with a 12V buzzer/horn from Radio Shack that cost about $6? I know next to nothing about electronics, but I'm thinking that there...

    Maiden Voyage

    Not really a SHT, but I felt so sorry for this guy I had to tell someone.<br /><br />Arrive at campground for our annual vacation. Was late in the day, so the family decided to just "hit the beach" rather than go out in the boat. <br /><br />As I was watching the kids swim, I noticed this...

    1986 140hp Evinrude<br /><br />Discovered that the powerpack on my motor isn't the correct one!! I'm thinking that it got changed during troubleshooting at one of the marines I took it to a couple years ago. Hasn't been running quite right since.<br /><br />I've now got the correct one and...

    Weak Spark?

    140hp & 225hp..Same Carb Body?

    Hi all,<br /><br />Due to the emulsion tubes in my 1986 140hp Evinrude carbs starting to disintigrate, I need to replace the carb bodies or the entire set of carbs/throttle body (the tubes themselves seem to be next to impossible to get on their own).<br /><br />I've located some carb bodies off...

    Sit-ups Anyone?

    After enjoying reading about everyone else's blunders, I figured it was about time for my contribution.<br /><br />Had a family reunion of sorts at a small lakeside resort in British Columbia. Had my 16 footer moored to a buoy about 20 yards from shore as there was no docking facilities. <br...

    Carb Jet Size

    1986 Evinrude 140 - Been having an ongoing stalling problem while accelerating. I know that it is fuel related as the problem can be overcome by bumping the primer a few times while accelerating. Once you get the RPMs high enough for the boat to plane, there are no problems.<br /><br />I've...
