This video is on point. Thanks for the great footage. I have the same generation motor but in 35hp and had to go through it very similar to what you are doing here. I have electric start and pull start. My motor is missing the pull start assembly. Whole motor came from a junk pile and I brought it back to life
I'm late to this video (my comment)... Every coil I've ever tested where there is a spinning magnet, produces AC voltage. your meter is set to DC voltage. If your manual says set to DC, you did fine. I didn't see that in the manual when you posted the picture.
I got a reading of 573 ohms on my charge coils following your steps. Same motor. I have no spark. Coils and power packs are good because I switched it with other motor and sparked. Thing is, I had no spark before on this same motor, changed charge coils and got spark, no no spark again with this reading I mentioned above. If im having the same problem (charge coils) what could be ruing my charge coils back to back?
Hey there and thank you for watching! I'm sorry about the delayed response. Is there any kind of indication they are striking the flywheel magnets? Even a little bit can really mess with the charge coils. Also did you replace the charge coils with brand new? Its possible the new one could be defective as well. I've seen it happen on more than one occasion.
@@EricGaskamp thanks for the reply. Lose plan disc under ignition components. Lose/worn out fuel pump outer rubber O-ring. Fixed those and it’s been having consistent spark with no dying from fuel shortage.
Hi there from australia! are you still playing with this outboard? i have the same one that needs gear linkage adjustment if i move the shift linkage forward its not enough to engage forward gear unless i really force it further all the way forward
Changed my powerpack and coils on my 98 johnson 25hp. Ran for 15mins and lost spark again. Motor is a project I bought non running. Stator apparently is from 77 to 83 so I dont have the charge coils and different assemblies. A and D on plug are 450 ohms. Stator looks old and magnets aren't pretty by any means. I have 3 yellow wires off of mine. Reading bounces around on those around .5 to 1 at most. Any ideas?
Thanks for watching! I would first start with comparing the part numbers from what your 98 is supposed to have as opposed to the one that is on your engine now from the older year range. If the part numbers are different, more than likely there are some small differences with could give you the issues you're having. Also make sure all the magnets are there and are clean. Do the same with the stator assembly as well. Where did you get the power pack from? Was it new, or a reman? Also ebay ones can go bad very quick or be bad straight out of the box. I hope this helps!!
Finally, another Astros fan!! Thanks for watching. Check the flywheel to make sure your magnets are in place. They have been known to come off which would lead to a no spark condition. Are those spark plugs the one that the factory calls for? If the plugs are too long they can make contact with the piston causing the engine not to turn over. I hope this helps some!
@@EricGaskamp htown native havent missed a game all season we are series bound! Ill have to check those magnets, i do have proper stator ohms. Yes im using the proper plugs
I have the same tiller except mine is electric start. Did you find out why there was no spark? I'm having same issue. It ran when I put it away last fall and now nothing. NEED HELP PLEASE!!!!!
@@crosstmandogman5027 Yes, that is correct. The carb is a little different, and there might be some other small differences, however I cannot remember them off the top of my head.
@@EricGaskamp thanks man. Ya I have the 20 hp model of this motor. Was running kind of rough but used seafoam to clean things up and ran way better. Never taken a carb off to clean before so these videos help. I'll try later this season and see how she runs.
@@crosstmandogman5027 I'm glad the videos are helping! I'm a visual learner so I'm way more comfortable about doing something after I've seen it done. I used to be scared of carbs until I watched some videos and did it myself. Now it's easy and saves so much money!! Oh, and I'm a huge believer in SeaFoam!
Just watched your video series on this motor.I made a video on lost spark on my 20hp Johnson.Almost ordered a power pack.I lost all spark after it ran great.Turns out it was just the ground for the power pack.Bolt going thru power pack also had the ground wire mounted behind it to the block.CleAned block and wire connector and all spark came back..Maybe your original power pack was good and you,lost ground like I did..Been about three years and still working.Watch my video.
It means some one gave it to me to work on and didn’t know if they wanted it but ended up needing it back. I work on these motors for free and for fun! Thanks for watching!

Super thorough and helpful for general trouble-shooting even for a noob like me. Great content!

That’s awesome! Glad to hear it! These motors are awesome. Thanks for watching and for the kind words!

Any idea what the white writing is on the moter? I have the same motor mine says rc in white writing on the side of the block.

When removing the flywheel to change charge coil how do I make sure motor stays in time ?
The flywheel is slotted so it will only go on one way if I remember correctly. Thank you for watching!
I’ve had to use a 4 pin cdi with 5 pins coming from motor, you wouldn’t know how to wire the kill switch in at all would you be able to help?
I can definitely look it up! It’s in the factory service manuals I have. Also, thank you for watching!!
Fabulous channel. Hello from Japan
Thank you! What is your favorite video?
Hey I have a 96 johnson 25hp electric start what shop manual are you using or what one would you suggest?
Hey! Thanks for watching! I use and recommend using only the OMC factory service manual.
Go stros, i have no spark in my ‘82 chrysler 75. Have power to everything. Any idea? Also dosent turn over with plugs in, plugs out spins freely

I believe it was the power pack. Once I changed it I had spark again. I would go with a brand new one though and not one off ebay! I hope it helps!
I have the exact same engine and it wont spark, what powerpack did you buy?
I bought a cheap one off ebay. I would buy brand new from BRP if you can!
I just bought a 14’ Vhull John boat for 800 bucks with this motor on it so this will be helpful!
You’ll love the engine and the boat!! Thanks for watching and let me know if you need any help!!
25 and 20 hp basically the same right ?
@@crosstmandogman5027 Yes, that is correct. The carb is a little different, and there might be some other small differences, however I cannot remember them off the top of my head.

Yeah I was kind of thinking that ground may have been my issue all along! Thanks for watching the series!! I’ll definitely check out your video!
"I just got this for free, but it's not mine" what does that even mean????
It means some one gave it to me to work on and didn’t know if they wanted it but ended up needing it back. I work on these motors for free and for fun! Thanks for watching!
The kill swiches are junk...
Work on that first!
Great point and often overlooked!
