35hp Johnson outboard--problem

12 posts in this topic

I gotta a major problem with a '98 Johnson 35 hp--long shaft--tiller. Starts easily--runs fine at all rpm for about 1/2 hour then starts sputtering, missing and dies out after running real rough for a while. Where I live this is just enough time to get into real trouble.

I changed gas tanks and gas lines, I changed plugs--I then replaced the CDI unit and then replaced the 3 coils. Next thing is the stator but they are expensive. Any of you motor heads got any idea's?

Ya, make sure it's spitting water out the back. You may need to replace the impeller.

Cicada may be right, It may be as simple as a warn impeler or just pluged intake. Sometimes our motors act like that, when they pull up for shorelunch and pull in some sand or a small pebble.

It's not a plugged intake--the indicator water is warm but not hot. I did have to replace the high limit switch a couple of years ago cause I plugged the intake with weeds. When that blew the motor ran fine but would only idle. Saftey thing I guess to keep you from burning up the engine. The rubber impellor looks fine when I take it apart.

Thanks guys

How long does it take to restart, or what do you have to do to restart?

I have to wait for it to cool off cold to restart--that can take an hour. I'm thinking it is more an overheating problem than a spark problem--lottsa spark when she is cold.

thanks again

Are you able to turn it over? or is it locked up?

It doesn't lock-up--you can restart it sometimes it just runs really rough--no power and missing.

I guess I would check the spark immediately when it happens to start narrowing to either spark, fuel, or compression. Does sound as though it is losing spark on 1 cylinder though.

I'd guess a coil but you replaced them. Next time it happens pull one plug and see if it smooths out. Do that with each cylinder.

It turned out to be a bad thermostat. I didn't even know it had a thermostat. Easy fix anyway--thanks guys.

    • Eaves would have been nice, better to the ducks than someone else. They beat us last go around but we were way better and Gibson won the game by himself.
    • Wow...Ducks get Eaves from Dallas for a conditional 2nd round pick...pretty cheap rental IMO..where were the Wild on this deal...oh ya we don't have a 2nd round pick 
    • Update:     Put some fresh gas in, sprayed the carb valve with some cleaner and cleaned the filter.  Also adjusted the idle speed up a bit. Runs great again!   Thanks for the advice and help everyone! 
    •   Nope...I think that is an original Bear55 Quote but Yogi Berra would be jealous if he were still alive.   Agree on the Blackhawks...when the season ends they will probably be the favorite to win the cup IMO so it will take an upset by any team to knock them off...would love for the Wild to be the ones to do so....it is getting very interesting as the trade deadline and playoffs time approach!
    • Out here (Virginia) our lakes are dirty and warm, and from what I understand, saugeyes thrive in those conditions. Our walleyes are all stocked since very few of our lakes have suitable spawning habitat and there is little to no natural reproduction.   Really looking forward to catching a saugeye just so I can cross it off my list!

    • Funny, that is the same face I get when I think of people voting for a reality tv star in as president. Worse yet he is some kind of billionaire, like the general public should ever trust one of those guys in public office.
    • More like Yogi the Bear but if I stole his quote my apologies.  Have to get that Chicago gorilla off our back, don't care if they win 4 of the next 5 cups, we just need one and I will be a happy camper.

      I'm not liking that they found some decent youth to play with Towes, we need to pounce before they fill in their gaps with depth and scoring again.
    • I am up to 27 in ND so far.  Waiting for more snow to melt.  Cold weather and deep snow makes the deer really group up out here and makes for easy shed hunting, but is really tough on the deer.  The 4th pic is one from some round bales that the deer were destroying earlier this year.   The biggest I find year to year is generally around that mid 60" range.  And I found that one (first pic) in early Janruary.  So hopes of finding a bigger one this year is low haha.
    • The only Merc I saw in Belize was on a parted out boat 75ft from water. Otherwise it was 70% Yammy's, 15% Honda's, 10% Suzzy's and a 5% hodgepodge of Evinrudes, Tohatsu, ect.......
