    Backfire but wont start - Low Compression?

    This is off-topic and it won't help you get your motor running, but it might help to keep it running well once you get it running (I suspect ignition timing or carburetors need another round)... You mentioned good gas, but not 93. Most of the 93 octane gas I have seen is automobile fuel with...

    Charging issue?

    One other thing to check... Turn off the motor and test the voltage on the batteries without any charging from the motor. If it reads 25V or 26V and your batteries are indeed connected in parralel vs. in series, then you might have your voltmeter on the wrong setting. That would be better...

    Mount an E-TEC powerhead on an older chassis?

    This is probably a really dumb question, but just a what-if... Several months ago I was grumbling about issues with my powerhead running rough at low RPMs and started to wonder whether any options existed to convert an outboard from carbureted to fuel-injected. A little bit of research...

    Johnson 40/48/50 14 to 17 spline shaft question

    My 1997 50HP is a 2-cylinder 737CC model and has the lower unit shown in the following thumbnail: 1995+ 40/45/50HP Lower Unit If I read this thread correctly, the OP @racemd appears to have mounted the lower unit from a 1988 40HP onto a 1995 40HP by swapping the driveshaft. 1997 Johnson 40...

    Sorry about that. I got if off a Google search. I guess I got a bad pic. It's removed.

    1997 Johnson 50 no power after stop/restart

    Update: I finally took some time to tune the carburetors again while on the water after all the other work I did on it. This engine has always had issues with one cylinder dropping out at lower RPMs, and it's bugged me for all the years I've had it. Once over 3200RPM, no issues. Below that...

    Johnson 40/48/50 14 to 17 spline shaft question

    Sorry for such a late response to this. I have a 1997 50HP and note the comment from @racerone that my lower unit is not the most rugged one out there, so this post intrigued me because I may one day find myself with a failed lower unit, and from what I see online, the older 1975-1988 lower...

    1997 Johnson 50 no power after stop/restart

    This one has me stumped. My engine seems to run normally on the driveway, and it seems to run normally for at least a period of time on the water, but after I stop it and restart, it becomes difficult to start, won't idle well, and it will die if I put it in gear. I'd appreciate any advice on...
