1984 Evinrude 150 stator

Re: 1984 Evinrude 150 stator

Yes, your understanding on the top half of post #19 is correct. I have had 1 wire that came loose from the plug (power pack to stator) that I have corrected and subsequently checked all the wires. That was very early in this process-before the stator was replaced. However since I have moved all the components numerous times I will check them again. I did get fire on all 6 for a short period just awhile ago. I had it with everything hooked up (stop circuit included). I put the plugs back in and tried to crank the motor...as soon as it tried to fire off the 1st time I lost spark on the starboard bank yet again. Since that, all I have done is disconnect the stop circuit again and retest timer base ohms (readings good).

Clean your grounds and replace any bolts that are used on the ground that have obvious rust.
Im wondering if that cracked outer magnet may be limiting your stators output.
Have you checked output voltage (preferably Vpeak) on the port side from the stator and the timing base?

Re: 1984 Evinrude 150 stator

No I haven't checked the output; but if I swap them (stator and/or timer base leads) to the port side bank of cylinders I can still get fire on those 3. My testing has been limited to checking ohms on the timer base because I don't have a DVA meter/adapter.

This proves that the stator, timer base, cranking revolution speed... all of it is okay!

What is different between the port and starboard side is the electrical plugs, powerpack, and coils.... and I believe that you did switch the powerpacks at one time and still got spark on the port bank which proves the powerpacks and their rubber plug connectors are okay. This leaves the three (3) coils and its rubber plug connector.

Having three coils fail all at the same time is very unlikely as is having all three pins/sockets with poor contact. What is left?.... Is that starboard powerpack grounded clean and solidly?

Re: 1984 Evinrude 150 stator

I have just finished refurbing the same motor and the big problem was corroded spring terminals at the plug end of the plug wires. Had to build new wires with new spring terminals and the sparks were then good. This corroding is a common problem on this motor and others. Shoot some WD40 into the caps and pull the wire and spring terminal out. I bet they are corroded.

Re: 1984 Evinrude 150 stator

Check the isolation diode in the packs, and as Joe said the pins in the connectors. Easy for one pin to get pushed in and not make connection.

Did you figure this out??? Im having the exact same issue....thanks

Re: 1984 Evinrude 150 stator

I was going to wait until we thawed out this weekend to test it under load before I updated...but here we go. As it turns out my stator (new replacement) turned out to be defective. It was working intermittently. I did not test it after replacement b/c "it's new; it obviously can't be the problem". Once it was replaced the 2nd time she fired right up...better than ever! Thank you all once again for the help and advice. Stratos, after fighting this I offer this advice: get a DVA adapter or either a peak reading meter. At ~$100 it is well worth the money! If you haven't got a manual buy that too. The info you get here seems much easier to follow but as a novice I found it very helpful to have the diagrams and specs staring right at you. Be methodic; check & clean all connections-I broke several by hooking/unhooking so many times while trying to figure this out. All said and done I ended up having a defective timer base and TWO defective stators!

Re: 1984 Evinrude 150 stator

Is your flywheel on that engine a vented flywheel? I am wondering if you have something else going on. Perhaps some incorrect/mixed parts. You stated that one of the flywheel magnets was "cracked," but 'not loose." (post #16.) Normally your engine model will have a 10 amp "solid" non-vented flywheel. The magnets should be embedded in the casting and it's very unlikely that they would be cracked on that type flywheel. If someone has replaced that flywheel with a "vented" one from the 84 150STL model- that model had the magnets glued in and they tended to both crack and loosen up with age. Perhaps you have mixed components on your engine. The vented flywheel was only used on the 35 amp charging system models, along with an upgraded combination rectifier/regulator. Perhaps you can clarify just what flywheel you have. The magnets excite both the ignition and charging coils on the stator.

Curious.... The first replacement stator that was eventually found to be defective, was that from Bombardier or from a third party company?

Re: 1984 Evinrude 150 stator

This motor is the E150ANCRS and it has a 35 amp system. The flywheel is vented and the magnets are glued (glue/epoxy of some sort...light grey color on the glue). The stator, also 35 amp carries a part number of 582574. The new one was found defective by the resistance test outlined in the manual (I have the "generic" SELOC manual). It was purchased through a 3rd party; local marine store and I'm not sure of it's actual origin. It's not CDI; it beared the OEM number. As for incorrect /mixed parts everything I've seen it seems this model had (has) the 35 amp system and all parts looked up supports this. Is this correct or am I seeing something wrong? Finding info on this particular model often proves difficult and many places don't even show that it exists. It seems it is the only commercial 150 HP they produced that year. It is the 75 year anniversary edition. Although it seems to be running well now if there are any deeper underlying issues I would sure like to find out while still on land! I will look this afternoon and try to get the part number off the rectifier/regulator to see if that matched the 35 amp theory also and will post my findings.

Re: 1984 Evinrude 150 stator

Sounds like you are all set to go with the engine. Sometimes it just takes a little perseverance. You can replaced the cracked magnet on the flywheel. Bombardier makes a factory magnet kit, complete with new magnets and a tube of the special epoxy to glue them on. Part number: 584304. About $ 30.

Re: 1984 Evinrude 150 stator

Good to hear your problem is solved, i replaced my stator today with a cdi unit, it seemed to have fixed it....i gotta run it on the lake to be positive as my problem was intermittent, but did occur 90% of the time.....what i found when i took the stator off was the two coils with the wires was leaking the black stuff, also one of the yellow rectifier wires was grounded on the stator, which might account for my battery draining while sitting.....got it back together, and seems much better, ill post tomorrow and let you know the final results....as i would like to hear your final results.........for the record, i hate when someone posts a problem, people take the time to comment and help find the fix, and the original poster does not complete the thread with final diagnosis and repair.....also, i have a great pdf file from cdi that runs you through the ignition system and tells you what and how to check......some checks are as simple as unhooking various wires and then running the motor...if you would like the file, pm me with your email and ill send it to you, its a very good read......good luck


Revised........i found a way to view the file online, here is the link.....i actually found this pdf very easily on the cdi website, that wasnt the way i aquired the pdf, but anyway here you go.......
