Major problems again

Recommended Posts

My 1984 40 hp Johnson is having major problems again. I think I know why it was running so bad last fall, it has ZERO spark now. I pulled it out today figured its rough running was bad plugs and put brand new ones in. I gave about 50 pulls and gave up. Even after priming and pumping as much as I could, the plugs were dry as a bone. So the carbs might have issues again. I put seafoam in the gas and ran it before I put it way in november. To try and get it working I put gas directly into each hole and had no sputter or anything. I pulled the plugs and tried multiple times but no spark. I put the electric tester on volts and tried the plug wires, coils, and the plug coming from the cdi (i tried the prongs in as many combinations as possible) and I couldn't get a reading anywhere. So my first question is how do I correctly test a CDI box? I even tried the tester on a 1981 25hp evinrude and I got readings out the plug wires, so it works. Compression is fine, top is 155'ish psi, bottom is about 160 psi. Good thing I bought the cheap gear lube today, because the moment this thing runs again, I'm selling it. I get to start my fishing season for the 3rd season in a row with my trusty 1972 18 hp evinrude converted to long shaft.

Does it have a saftey lanyard? If it does these switches are normally OPEN to allow the engine to run. When "off ", they close a ground circuit to kill the spark.

I don't know how to help you start the motor, have had my issues with a small outboard like that for several years and finally ditched it. But go get a socket the same size as the nut on the top of the cord winder. Then you can just use a cordless or corded drill to start it much easier. My arm almost fell off a few years ago and I was told of that strategy to crank a motor

That is a nice idea!

1st off, as mentioned above, make sure the kill switch is in the correct position.

There is not a test for the power pack itself. You have to test everything around it and rule out the other components. Most of these parts cost quite a bit, so it's very important to test in a systemic method. To do this properly and with confidence, you need to this with 1 or 2 methods. 1 is with a peak reading type meter (direct voltage adapter DVA) to measure peak voltage (230 +) or using an ohm meter to measure resistance and to check for opens and grounded circuits.

You can pm me your email if u want the test specs

Well I don't think a drill will be able to turn the motor over, at least not any cordless we have. It might work for a smaller engine, but I can pull start it just fine, well when it ran anyway. It doesn't have any safety switches that I know of, no lanyard shut off, and to turn it off is just a button in the handle. I disconnected what I believed to be the shut off and there was no change. I'll just have to test it completely.

Sounds like the Electronic Control Module/switch box fried?

Thank you very much boat fixer. I tested ohms before the CDI and it was good, and after had nothing. I'll be ordering a new one, hopefully it is all I need.

Yup, CDI. It started in 3 pulls, but its idle knocked over my pop, and my tool box. Now I remember why I hated it so much, its not reliable, not that powerful for its weight, and its idle has popped rivets out of the boat. BTW its probably for sale, I'll check to make sure tonight.

    • I’m in a similar situation right now and I am “freaking out” how did it work out for you what paper work did you file? Who did you reach out to?
    • Did someone pee in your charcoal 😁?
    • I like to see the fish that gets away verses not. A few weeks ago, I was trolling for walleyes on the SLR and while reeling one in, something grabbed a hold of it and fought hard for a while but chewed the walleye pretty bad. Trolled over the same are 20 minutes later and caught another walleye and this time it didn't let go and I saw what was eating my walleyes and it was a huge musky that got close to the boat and snapped the line and left with my crankbait and fish. So, the one I saw that "got away" was a cooler sight than the mystery fish that attacked my walleye that I never got to see earlier that day
    • Besides the motor on the back, I don't see much a difference between an old boat and a new boat.   It's not like new boats parallel park themselves.           
    • and still end up with an old boat as was said earlier.  I think it's more a labor of love for what we have...
    • looks like it got corrected! thanks Rick
    • Looks fine to me @rundrave :D
    • Hello from the NW Angle!

      Surface water temperatures range from 65 in the morning reaching low 70s during the late afternoon. 

      Minnesota has been best in shallower areas such as the Flag Island Flats (5-9 ft.) Prime time being the evening bite with many nice fish including a 31" beast. Deeper water around Four Blocks and LIttle Oak are providing good action for Walleye/Sauger. Orange has been the top color. Even with the recent Mayfly hatch and plenty of crayfish in fishes bellies, (Walleye, Sauger and Northerns) the fishing is awesome!

      Canadian fishing has been the best using bottom bouncers in the mud with gold being the most productive color spinners. Jigging will produce fish around structure with larger Walleye/Sauger coming out of 26+ feet of water. Pike and Muskie action is somewhat concentrated to underwater weeds or occasionally while jigging for walleye.

      We hope to see you soon!

    • I think you'd probably have to develop connections to find the right boats at the right price.  If you could also increase the number of boats you do in a given season you could also start buying some materials in bulk which would help drive material costs down.  Still I'm guessing margins would be relatively thin, certainly not a get rich quick scheme.
