johnson outboard problem

[JPROCTOR]

I have a johnson 115 that will not get up to the max rpm the throttle is wide open however it only runs about 2300 rpm instead of 5500-6000. It was running fine, but has sat for about 4 months. Can anyone give me some suggestions ???

compression check....then a spark check.. then come back and let us know the results...then fuel checks last....sitting for 4 months could prob mean fuel probs.

you can buy a compression checker $30 and a spark checker $10 at autozone.

His johnson won't get up ;D

Sorry, follow the advice above.

I'll add, how old is the fuel?

Was it stored with fuel stabilizer? How does it idle? When you can't get up your JOHNSON ;D, what exactly does it do?(runs rough, surges, chokes, spits swallows)

The compresion check is fine, the spark check is fine. The fuel was just replaced when we replaced the tank last week. The fuel is flowing fine.

It seems to be limited to 2300 rpm it will jump a little like it wants to get up to speed, but it doesn't.

I do have another question. water is coming out of the hole where the thermostat purges and it is constant. I think the thermostat is stuck. Here is my question, is there a sensor that would limit it from running WOT if it thinks it is overheating.

What year engine is it? Have you checked to see if the timing pickup is moving with the throttle linkage? It isn't uncommon for the pickup base to stick after sitting for awhile.

Gotta hate it when you can't get your Johnson up ;D

With all the boob shaking going on here, I don't see how anyone's Johnson aint up.

look under flywheel to see that the timing advance hasn't come out it's hole

Mine hits the limiter NO PROBLEM! ;)

just to eliminate the obvious, check the fuel vent, and check the primer bulb. then go ahead and run a compresion test and spark check to make sure you don't have anything serious going on, if that checks out ok, then go ahead and rebuild the carbs and fuel pump, clean out the fuel system, even if its not the main problem, its probably due

Apparrently I have an issue with my speed limiting overheating warning(S.L.O.W.) that is causing my RPMs to drop so low. I am not sure why it is activated though. My pump is working fine and the thermostats are working. I guess I will have to grabe a manual tommorow and see how to correct or bypass the problem.

Is the alarm going off? What Year? I have a manual sitting right next to my computer, or I'm sure SKOOLS can site the JOHNNY-RUDE book for us if needs be. Really need to know what you have to help you figure it out here. There is a chance that the warning horn has gone out and is causing your problem, or the diode(depending on year and model) could be blown and shorting the S.L.O.W. sytem to stay in start up self test mode which would limit it to 2500.

Were talking about a FICHT right?

If so you need to hook it up to a computer with the FICHT software to read the codes and then match the code in the manual to tell you which of the many sensors is screwed up.

You can get the software and a manual on ebay or order both from your local dealer. It's a hopeless guessing game without hooking into the computer and having the FACTORY service manual.

On my 150 FICHT (when I used to own one) . . . RPM reduction (slow mode) kicked in a few times . . . I forget why but there are a number of different combinations that cause S.L.O.W to kick in.

Good Luck . . .

[JPROCTOR]

Checked spark again and found both port side cylinders were not firing. Plugs, wires and coils are new and good.
It could only be the stators or powerpacks. I can not find a service manual locally. Can any one tell me what the testing proceedures are for the stators? I believe a stator must be bad.

Wouldn't stator affect spark to all cyls??...if bad on one side, I'd be lookin' hard at power-packs ;) ... those OMC power-packs go out quicker than a $5 Hooker...Not bashin' ...I had 'em B4, but it's a common problem... ;) ...

[Skools Out]

yeah stator affects all it will be other test the coils and the power packsjust because they are new doesn't mean they are good. take the plugs out hook to the coils and turn over check each for fire then take the bad ones and hook the wire from the powerpack to a different coil see it the problem follows then you know it's the powerpack. you can swap them see it the bad coil fires that way you have checked all. and and look under the flywheel make sure the magnets aren't loose and out of place.

[THEFERMANATOR]

Reading my manual it appears you have a cross-flow engine with the very basic ignition system. Do like SKOOLS said and swap the coil leads around and see if the problem follows the coil or if it follows the lead coming out of the powerpack. If you got spark to 2 cylinders your stator can most likely be ruled as good, which leaves your timer base and powerpack. If you've got a peak reading volt meter(must be a peak reading volt meter or an analog with the adaptor to test it) you can go through and check to see if you've got a charge coming out of all 4 leads on your timer base. But try swapping the leads or swap the coils from one side to the other.

[randlemanboater]

Seems like I remember something, maybe the stator, being a 2 part item that you can lose half of? Been 10 years since I had a 2 stroke OMC but I had the same thing happen.

mine was the powerpack!! I got a brand new OMC from ebay for $55 including shipping.

His is a 95 with the single powerpack and 4 coils similar to the sytem that the V-4 90 degree loopers used. Sounds to me like a short in the timer base harness or a bad ground or connection on the coils since the port coils share the same plug for there source to the powerpack.

I had one display these exact symptoms and it was just a couple of the spark plugs were fouled.
