    1975 Johnson 6hp, dies under load

    Solved. One of the points was not closing all the way. Hadn't touched it since tuning the timing after replacing them a few years ago, but there it was. Adjusted the set screw and tightened it down, she runs great again. Thanks for the input, hope this helps someone.

    Yep, it is correct. Also I was mistaken earlier: I had the driveshaft connected in the lower unit with forward gear engaged so I was spinning the impeller, hence the extra torque needed.

    Ok, got home after work and gave it a spin in neutral, it is super easy. Turns about 2-3 revolutions before it stops. Followed the service manual pretty carefully so I feel good about it being aligned properly. Plus it worked fine last year and none of that was disassembled since.

    With the driveshaft disconnected I can spin it with two fingers. With the flywheel on I can turn it with some force. Ordered a 10-pk of packing washers!

    I hate having to post another one of these threads, but I've read just about every other one on the internet. It's long, I hope some of you make it through the whole thing, lol. As stated above: Worked great last season, fogged out, stored upright indoors. Over the winter I pulled the power...
