    Johnson 20 HP. Ignition Problem

    The plug that connects the charging coil and timing trigger to the CDI has the wires in it which have to be replaced with the new ones. Can anybody suggest how to remove them?

    Johnson 20 HP. Ignition Problem

    The parts ordered from CDI. Very helpful customer service, assited with parts. Changing the charger coil and timing trigger. For the wiring an Amphenol extraction tool has to be purchased to remove and install wiring at joining plug to CDI. I'll update when complete.

    Johnson 20 HP. Ignition Problem

    Hi fellow Johnson outboard owners. I recently purchased a project boat and motor and experiencing ignition problems. I have gone through the online CDI checklist all readings seem to be good. I replaced the CDI, thought it might be a good idea given the age of the motor. The motor is a 1987 , 20...

    I was able to fix the issue. It would appear when the previous owner replaced the impeller he had not seated the rubber spout into the the tube properly, water was leaking. At this point I don't trust any of the work which was done on this motor Alls good runs great, one question, there are...

    Hi outboard owners. Are these holes for exhaust or should they be plugged? Crappies are in hopefully I can get this figured out. Tks.

    Thanks everyone for your great advice. I dropped the lower end to find the previous owner had probably replaced the impeller. When reinstalling the lower he had bent over the tube coming from the impeller housing not full engaging on the copper inlet pipe. The housing rubber spout piece was...

    Mercury 9.9 hp.

    Thanks for everyone's replies A pressure test was done on both cylinders, 120 each. Looking at other motors in buckets the water isn't as full of exhaust oil, maybe it's just me but there's alot. The gaskets were reversed letting water pour into each cylinder, just confused at how it ran ...

    Hi Mercury outboard owners. I recently purchased a merc. 9.9hp for my son and myself to enjoy fishing this year. Although the previous owner indicated the motor worked fine and a short test ride was done. Unfortunately the motor has ended up being nothing short of a dud. The initial trip the...

    Yes it's an eye opener, I don't operate that way, some people are dishonest. Finally got the gaskets, installed both, fired it up. I noticed smoke , which I assume is from the exhaust come out of the tell tale. Is this normal? The tell tale before did not shoot exhaust out before the water...

    Mercury 1999 9.9 hp

    Found the problem! Removed the casing to expose the pistons, the previous owner had reversed the two gaskets, water was entering the cylinders as result of the different gaskets. Also it looks like the plate was not torqued in a pattern recommended. Searching now for the torque pattern/values...

    I performed a compression test on both cylinders, both came out as 110 psi. This reading is more than acceptable. Next step is new gas oil, don't know what else can be done.

    There is no water coming out the plug holes, just water on the plugs. When I ran it it would pull over after every time, next day in neutral the pull cord wouldn't move. I'm not leaning on water on the fuel, seems to be all good. I'll do a compression test on the cylinders.

    Tks. I drained the fuel from the tank into a clear jug, doesn't seem to have water in the fuel, constant blue colour, 50:1 mix. I have attached a photo of the plugs. The motor has been run in fresh water, no corrosion that can be seen. The motor runs and idles as it should.

    I recently purchased a mercury 9.9 hp to take my grandchildren fishing. It was reassured by the previous owner the motor was in good working order. The second time taking the kids out the motor seemed to work fine, however when I went to use it the next day I couldn't pull the cord out to...

    I removed the broken part. How does the new knob go back in?? I'm afraid of snapping the plastic . I can see the swirl inside the assembly which rotates with knob.
