After running engine is hard to start _ Dies after I engage engine

[mrod322]

225 evinrude trexeob 1995

I rebuilt my carbs full rebuilt (rebuild kit) etc. Replaced my power pack and everything seems good. So decided to go fishing...

At the ramp engine fires up great no prob. Once I hit reverse out of the ramp engine dies, so i figured it was just a fluke. So i restarted the engine and went down channel good RPM 800-900 no problems after channel hit it hard 5000 rpm for about 15 mile (looking for dolphin) finally hit a school caught about 6 then needed to move but here is where the problem started.

When i started the engine it started right up then i engaged and the engine died. Started again about 6 to 7 times. Got pissed off put the chum bag in and waited for the fish to show up again(they did) so after the frenzy ended i started the engine and reved up in neutral 3000 rpm or so waited a bit and put in gear a little hard about 1000 -1100 rpm and finally was able t get moving.

I notice after the engine is hot or running for a while it acts up when putting in gear. It always starts but when engauge it dies. I removed the black and yellow kill switch cable same thing.

Any input or test is greatly appreciated.

start off with the basics , compesion test , spark test , and check you fuel lines to make sure there are no blockages. before i would look into the carbs i would try to imitate the heat off a good long wot run with a hair dryer. i would apply the heat to the coils and the powerpack . to see if you can get her to act up. this process can take a little while but sometimes it can take you to faulty coil that is on its way out.check for cracks in the coils too.good luck!!

Re: After running engine is hard to start _ Dies after I engage engine

I dont really think its something when the engine heats up because i can run it at 4k 5k rpm forever and no problem but when I slow down and idle and start up again is when i have issues.

Does anyone know what should be the running temp?

I put a temp gauge and a sending unit on the block but not sure if accurate. I have the upgraded system tach and it doesn't loght up the hot nor the alarm so i dont think its overheating but just what to make sure where im suppose to be.

Thanks,

Mike

I have exactly yhe same problem with my 87 model 225.Did you find out what was the problem?

Re: After running engine is hard to start _ Dies after I engage engine

I am having the same exact problem with my 2000 90hp OIS2000. It starts right up and runs at WOT all day long. Shut it off and let it sit for anything from 5 minutes to 2 hours and try to start it up and thats when it gets interesting. Starts up but as soon as you put it in gear it dies. Keep this cycle up and sooner or later it doesn't even want to start. Finally, let it sit again for awhile and then try to start and floor it and it will hiccup and then take off. Will run at WOT all the way back to the dock. Also, it doesn't want to idle after running at WOT sometimes. I am torn about what the problem might be. I thought it would be ignition related but then someone mentioned fuel related. All carbs were recently rebuilt about a year ago by the boat shop.

Re: After running engine is hard to start _ Dies after I engage engine

I have a 94 200hp Evinrude that does the same thing. Runs great at WOT. First start up in the morning and it is fine. Run engine for a 20 minute run then stop and fish for a while and it starts right up but when you put it in gear the rpms drop to about 450 and it stalls and dies when you accelerate. Very Frustrating. I too would like any ideas. Give me some ideas and together maybe we all can figure this out.

Re: After running engine is hard to start _ Dies after I engage engine

Look closely under the flywheel. There should be a (approximately) 1/4" gap between every magnet. If any magnet has come loose and touching the other, the flywheel will require repairing or replacing.

Look closely at the two large black coils located at the rear portion of that stator. If either one of those black coils is dripping a substance down upon the timer base and powerhead, replace the stator.

The above stator condition results in weak, erratic..... and eventually no ignition (spark).

Re: After running engine is hard to start _ Dies after I engage engine

Thanks for the tip Mr. Reeves. Just pulled my flywheel and checked the magnets and looked carefully at the coils on the stator. It all looks very clean and sound from what I can see. Idles fine on muffs. About 1100 rpms. Idles fine on initial start up. After a nice run when you come off plane to idle speed in gear it will idle at about 700-800 rpms for 30 or so seconds and then all of the sudden it will drop to 450 rpms. Its just like someone turned something off. It starts up again easily but we start all over again when you put it in gear. If you are very quick and nail it and you get lucky it will take off, but usually it just dies. If you try to accelerate gradually it will die for sure. I am very frustrated with this and am out of ideas. I see no visible signs of problems on the cylinder coils. The engine has been decarbed. As I said previously it runs fine at WOT and thru most of the acceleration curve. It will accelerate smoothly from idle the first start up of the day or after a good long cool down period.I am not trying to Hi Jack this thread it just sounds like a lot of us have very similar problems.

Re: After running engine is hard to start _ Dies after I engage engine

I am chasing this very exact same problem on my 1998 Johnson Fast Strike.Runs great at WOT until you stop to fish for awhile...then the problem starts.I have had carbs totally redone,new plugs,new wires, new power pack,new optical sensor still no fix.Seems by searching the forums this seems to be a common problem that nobody has ever come up with a definant fix for

might be heat soak, try this

when you come off plane let it idle and pump the bulb up when you shut it down. If that fixes it then its heat soak. Not enough air flow under the cowl.

Re: After running engine is hard to start _ Dies after I engage engine

Please explain this Heat Soak condition, I do not understand how pumpimg the fuel bulb could help with lack of air under the cowling. I have run mine with the cover off and even the air silincer off and the problem still exists. I will try what you say though because I have nothing to lose. Thanks.

Re: After running engine is hard to start _ Dies after I engage engine

Same problem here. 93 Johnson GT200. Run it for 30 minutes and then stop to fish. Starts up OK and idles fine in neutral. When put in gear RPM's steadily decrease until it quits. Try to quickly put in gear and apply throttle and it quits, sounds almost like it floods out. When you finally get on plane after multiple attempts it runs great WOT. When you get to the harbor and try to idle in the problem starts all over again. When you try to drive on trailer it quits every time. My mechanic drove it and said it was the timer base. He replaced it but it did nothing to the problem. My question is could it just be set to idle too slowly? After it gets hot the idle speed in gear as very low, around 400 rpm. Motor was recently rebuilt as well as carbs.

Have you tried pumping the bulb when it won't go?

have you checked the lower unit? could be something dragging.

I would baseline the engine, compression, spark gat test, carbs
and put a timing light on it when it gets balky, need to sort out whether its fuel or spark.

Have you checked the ignition pickup roller?

Re: After running engine is hard to start _ Dies after I engage engine

Pick up roller is complete. Compression is great. Bulb is firm and squezzing makes no difference. Carbs recently rebuilt. Lower unit seems great. Changed oil recently and there were no signs of metal or water. Have tested spark with a gap tester and the spark is blue and crisp. Any other ideas?

Re: After running engine is hard to start _ Dies after I engage engine

Thats good work on the static testing, without special tools anyway.
7/16th inch spark gap right?
just checking your checkings.

Now it needs dynamic testing on the water at operating temps.

A timing light will show if its dropping a cylinder when it starts acting up,
its best with 2 people, all you need to do is keep moving the timing light pickup clamp, leave the clips on the battery.

if all cylinders are sparking then try spraying fuel/oil mix into the carb throat to see if it picks up.

also test for heat soak whilst your out there.
Heat soak test was given yesterday.

something has to crop up.

Re: After running engine is hard to start _ Dies after I engage engine

I have a 2003 Johnson 150 and have had a similar problem twice since I bought my boat/motor two years ago. The first time - about a year and a half ago, a mechanic eventually figured out it was a corroded "shift switch" at the engine. Recently, I began having the problem again. The mechanic adjusted the carb's at the shop, purred like a sewing machine, engaged the throttle, ran great; but when I launched the boat it would shut off at idle. When I eased up to a dock or tried to load it would shut off. Took it back, they put it in the river and adjusted "carbs and spark" and it runs fine now. Evidently it needed the "back pressure" from being in water to be adjusted correctly. I'm clueless about engines so if any of this sounds bogus - it came from my mechanic! Hope it helps. I've still got a cranking issue. The engine never has cranked easily since I got it. I can put it in the river 5 times and 4 of 'em I have to pull it out, dry spark plugs, then crank it on the hill. A few times it never cranks at all. Turns over but doesn't fire. I take it in to the mechanic....and it fires right up. They think I'm crazy. It's in the shop now.

Iwill try this weekend with the dynamic test on the cylinders. My problem with that is my timing light plugs into 120 vac and not a 12 vdc battery. Is there any way I could use my digital VOM. It has a feature for checking amps by clamping it around a cable or wire. I just don't know if that would be a reliable test. What do you think?

 

[jonesg]

Re: After running engine is hard to start _ Dies after I engage engine

I'd either get a cheapo timing light or an inline flasher from the local autozone, its worth having the right (cheap) tools.

Unless you have a voltage inverter.

Hi Mark, start a new thread and let us know what the "shop" says.

Re: After running engine is hard to start _ Dies after I engage engine

I've had a similar problem with a 84 140 crossflow. My mechanic said that after shutdown the new gas with ethanol would evaporate out of the carb and make a restart difficult until it cooled. Once it was running the cooler gas from the tank would cool the carbs and it would run OK after a few minutes. It sounds like your problem is more involved but this could be part of it.
