1987 Johnson 110 just quit

Recommended Posts

Hello all, been a while since I've posted but I have a couple questions that needs some answers.  the afore referenced motor was running fine, I fouled the carbs when I ran out of gas, after I got them cleaned out the motor was running fine, while running it on the water house with the ears one day the motor just quit.  Now there is no fire or anything, the stator is putting out the correct voltage but I'm loosing it between there and the plugs.  On another note, when I put it on the pressurized hose to try to start it now the water does not come out of the "pee hole".  If memory serves me before the motor quit it did, I sure hope that I haven't really messed the motor up.  So my two questions are could the fire problem be the power packs, as of now it isn't the stator, the kill switch or in the key switch.  Another is should water be pushed through the engine when on a pressurized hose?  If so and I ran the engine without water I guess I could of destroyed the head, but would that cause no fire?  Any help is appreciated.

when running on the ears you should defenitely have water circulating through the engine and coming out the pee hole. Sounds like you have another problem.

Outboards are not set up to run on the cuffs. Even though a stream of water will circulate it is not good to do so for any lenght of time. It will burn a water pump and/or motor quickly.

It's ok to start and do a quick check, but make it a very short duration.

thanks, I am afraid that I may have ruined the motor.   :-[  I have a mechanic coming to look at it, may be in the market for another boat

I'd say you overheated the engine but if there isn't any juice making it's way to the ignition leads, it may be indicative of something else and, hopefully, a cheaper fix.  Don't lose hope yet!  I'll be curious to hear what the mechanic says.

I think I have a different take on this. The sudden quit you describe is characteristic of spark quitting whereas overheat usually start running rough, sputter, or something semi-sudden.  If the engine is not running then the hose is not going to push water through the water pump.  Unless you have some other indication that there was an overheat problem I would focus on your spark problem and not worry about the water flow.  As soon as you get the spark problem fixed I would double check water flow with the engine running.

Check the kill switch if you have one.

Visually inspect the motor wiring, and fuel lines.

If it did overheat, it should start back up after it cools off.

I had a 140 evinrude overheat while at full throttle.

I waited a hour, then it started right back up.

First off, the pee hole could be stopped up, dirt dobbers love ready made holes and it's very common for them to build nest in them, or something else could have stopped it up.   It also takes a little time for water to fill the exhaust chest and start coming out.

As for running one on a hose/muffs, it doesn't bother one as long as you turn the water on before you start it and off after shutting engine off.  Running one dry is what destroys a water pump.  I've run motors for 1/2 hour at the time on a hose when I don't feel like messing with the tank.

I don't remember if the V4 has one or two power packs but there is a black or black white wire on the terminal strip going to the  power pack.  Disconnect this wire and see if you have fire.  If the motor happens to start, the only way you can shut if off is to reconnect that wire, short it to metal on the motor, or choke it down by covering the carbs with your hand.  That's the kill wire, the key switch/kill switch shorts it to ground to shut the motor off.

It's not unheard of for a power pack to go belly up all at once like that but usually those they will start running bad before they just quit.  Then again, that may have been your problem when you thought the carbs got fouled and it finished dying while you were running it on the hose.
