    No spark on bottom cylinder

    i thought I had this thing whipped, but I've lost spark again on the bottom cylinder. I double checked the plug wire connection. I had previously cleaned and gapped the points and I got good spark and the motor ran well but was still missing occasionally at high rpm. Since I had only shoved the...

    73 Johnson 6hp Flywheel Off

    Thanks to all who contribute on this site; I was able to get the flywheel off easily and visually inspect the ignition system. I am impressed how clean and "not old" the parts appear. This motor has been in my family for 20+ years and to my knowledge the ignition has never been checked. I am...

    What next?

    so I completed my first diy carb rebuild and fuel pump rebuild. I also installed an in line fuel filter under the cowl. Took the boat out and it starts and I got the idle adjusted, but it won't run past maybe half throttle. It's like it's governed or something. Could this be because of the fuel...

    What is this and is it normal?

    First time DIY Carb Rebuild. I am also rebuilding the fuel pump and replacing fuel lines to be safe. See pics below. What is the black stuff in the yellow bowl after cleaning carb? Black buildup seen in intake? Lastly, reddish gunk in fuel pump parts?

    Starter Troubleshooting

    Pros, I have been working hard to get mine and my father's boat ready for fishing season. Dad's mid 90s Johnson starter just spins and the gear doesn't come up at all to engage flywheel. His starting battery is less than 1 yr old and he charged it for 24 hrs (2 amp) before we tried to get the...

    Guys, I'm almost to the point where I am going to tear into my 73 Johnson 6hp Seahorse. I want to rebuild carbs and inspect/clean/maybe replace some of the ignition parts. Where can I find some videos on some of these projects? I have done the typical searches but there isn't much besides...

    Sluggish and Surging

    I am hoping some of you master mechanics can help point me in the right direction. I have a 73 Johnson Seahorse 6hp. I took it out for the first run of the year Sat. It started fairly easily but doesn't seem to run as high as it should at full throttle. There are two issues I am noticing...

    Need Help

    I recently paid $160 to have my older 6hp Johnson Seahorse lower unit serviced, fuel filter cap, gasket, and screen replaced, compression checked, and tank tested because it hadn't been ran in a couple of years. The mechanic placed the motor back in the tank, started, and ran it very easily...

    Prop repair

    I have a 73 Johnson Seahorse 6 hp. Motor calls for an 8 x 7-1/4 2 blade prop. I noticed last summer when I got the motor from my father that one of the blades is bent badly. Looks like it caught the bottom when the boat was being pushed back from shore or launched. The bad news is the motor...

    What year?

    I am sorry if I should be able to find this on old threads, I have been searching for a way to look up year models from Serial Numbers and can't seem to find that tool on here. Serial # J3733140 Model 6R-73s Does that mean it is a 73? Also, best recommendation/place to order parts on-line?
