Motor Problems 115 Johnson

6 posts in this topic

Quick question for everyone.

Just got a call from my fishing partner Groloe, he said he just pulled off the lake and had motor troubles and can't get his motor to fire off.

He has a 115 Johnson, only 3 years old.

There is power and the motor tries to start, and he can smell fuel. He is at the cabin now with boat out of the water.

I told him to disconnect everything from the starting battery except the motor (reason a new depth finder was wired up this week in between the last time it was on the water and this one, seems to be the only thing that was changed, but I know it shouldn't be the cause if we have power to the motor).

Next I told him to check for spark, which still needs to be done. After this I have a limited idea of where to proceed next.

I will be heading up there soon after work this evening and would like a few ideas before I head out.

Thanks

Make sure that all the lines in the fuel system are connected and tight and that there are no leaks. Just because you can smell fuel doesn't mean it is getting to where it is supposed to.

I have been fighting a similar problem with my evinrude 70. It didn't get fuel pressure to the carbs and had to be manually choked on occasion. Some lines where bad coming out of the VRO pump.

I hope you do not have the same problem that I had about a month ago. My 115 HP Johnson had the same problem motor died and I could not get it too start. I ended up burning a piston on my motor. I am still waiting to get it back the whole powerhead has to be replaced. I hope you have better luck with your motor and it is something minor.

I think we can rule that it was the operator who had the problem!! tongue.gif

IMO that engine is flawless!

upnorth and donz, I just had a 60HP jonhson burn out a piston for the second time I learn slow but now I would recomend to everyone to mix your gas and oil as the vro system will fail sooner or later and why have trouble, just disable the thing and mix your own, I had old Jonhsons last forever before they invented the vro

    •  I use a Digger mount on my ATV and sled.  Its fast and easy.   I'm on the ice everyday testing and tweaking Nils blades. I rack the auger on every blade change and some days that could be 20 times so for the me the Digger is exactly what I need.  The clamp on the Digger makes fast work of securing the auger and removal.   The height of the Digger frees room on the rack for more gear.      Once in a while we'll take my buddies ATV out fishing.  Hes got no auger rack so we'll bungie the auger to the ATV rack. It works but it makes me appreciate the Digger rack all the more.   Any rack would be an improvement there.   In the past guys have posted their homemade racks and I hope they do so again.   
    • Currently have a couple empires. Most likely toss one of them in. If I go with a furnace I'll use a small plug in step down transformer 120v AC to 12DC. They are cheap as hell basically an oversized cellphone charger.
    •   You realize the only ones taking Calexit with any seriousness are conservatives. Which means conservatives are the ones falling for the Russian propaganda. Liberals say it sarcastically because conservatives think the country would be better off without the "coastal liberal elites" (even though California pays in $405 billion in federal taxes and receives only $344 billion in federal spending, meaning the rest of the country would be $61 billion poorer without California).
    •   As in the one that lets me use his cabin for Turkey and Deer hunting!
    • So Bear, please describe what your policy on those drugs now banned would be, in as much detail as you can.     I am really wondering what the alternative envisioned by the "stop the war on drugs" folks is.      
    •   Bear, I explained why we are stuck with the two party system.   If you don't like the two we have, you need to "pull a trump" and take over one of them.     Good Luck. 
    • Actually only one species of bumblebee so far.     I have no idea how one distinguishes the species of bumblebees.

    • I would suggest using non-oxy gas also!
    • I highly doubt it needs carb kits if only sat that long. Draining the carb bowls and spraying carb cleaner in there can clean things up a lot and loosen sticky floats. Should be a main jet on each carb you can pull to drain carb bowls and spray into and clean jet. Put in fresh gas with seafoam in it and new plugs and it will probably run. Impeller is a pretty easy job to. Should be able to find a video on u tube on how to do it. I would drain my carb bowls on my old 115 2 stroke every spring and you would be surprised at the slimy stuff that came out of them sometimes and that was just sitting over winter.
