Johnson stops dead!

I ordered the power pack today from Amazon and it will be here tomorrow morning between 4 and 8 A.M., so to get it before Monday, it costed me a few bucks extra. Total with taxes & free delivery was $48.75. The brand is Sierra, part #113-2453 and it is a new one, not used, States it will replace a few different part numbers, and one of them was the part number I need, so I bought it. Never had any problems myself with Sierra parts in the past. I figured for the price, I will change the current one that I had (removed it today) and just hope it solves my problem of the motor just shutting off while cruising speed or WOT. Will be installing the new one tomorrow but cannot get back onto the lake until Tuesday or Wednesday, weather permitting . Thanks again guys!

What is the brand of the new power pack for 43 dollar!!
Check if it is a Chines manufacturer.
In my opinion keep away from Chines aftermarket parts.
It is crap, buy a OEM, Sierra or CDI part and you will not be disappointed.

Yep, I bought a Chinese carb kit a few years ago and it was garbage. Ordered OEM a few days after I put the Chinese parts in and what a difference it made! I hope Sierra is not a Chinese brand , but I never had a problem with Sierra.

Not sure if your getting OEM or not, but if you aren't, I'd think about that one.

Might just be me though....last week I just purchased 2 brand new ignition coils for my 85 30hp even though they were working. Coils lose "energy making abilities" when they get older and just like the power pack if you need them buy oem if it's available.

Best

The coils checked out on line look like they are plenty cheap enough to replace as well as my power pack. I want to change the power pack by itself first to see if that is what caused my problem of the motor just shutting off like someone turned off the key. Did ot bog down or start missing or coughing or anything like that. It just totally shut off under load and would not start back up until after about 10 minutes or so.

Could be the coil under the flywheel....

My rule of thumb, buy oem first if it's available and cost is okay, Sierra next and then CDI or nos/eBay. Many agree with this strategy.

Let us know how it goes.

So, I am assuming that Sierra is a pretty decent brand to purchase. I usually buy Sierra parts since I tried some Chines parts a few years back and learned about them Chinese parts really quick. Never again! Never had any problems at all with Sierra. Thanks.

I have to pull the flywheel off.
With flywheel magnet stopped at the trigger coil. I can feel a slight flexing of the coil as I slowly move flywheel a little back and forth. Redo the screws before rubbing occurs.

I watched a few videos about removing the flywheel and it does not actually look too hard to accomplish to replace the coils under it. The videos I watched did not show anything about a stator on any of them. Does my motor have a stator on it? It is a conversion from a tiller to a remote motor. Always was electric start. Will I have a problem removing the flywheel if it has a stator? Thanks again. Sorry about all of the questions, but I am really learning things on here that I am attempting on my own with all of your help.

The components under the flywheel can be tested without removing the flywheel.------And stator or not makes no difference in removing the flywheel !

only time I've ever seen a motor just cut out, it is electrical. like if it goes out like someone hit a kill switch. and everytime a loose or bad connection. failed kill or key switch, or anywhere you can just have a bad/failing connection.

I replaced the power pack on it today. Being a 1983 and probably all original under the flywheel, I am seriously thinking about removing the flywheel and checking the condition of the coils, stator and points and replacing it all while I have the flywheel off. The parts look cheap enough (other than the stator) for me to buy for the added insurance that the motor will run good again. If stator is good, I will keep the old one. It's a 1983 35 H.P and it looks and runs like it had very few hours on it. Ran great until this problem came up with it just shutting off like someone shut the key off! Can anyone tell me what sized socket I will need for the flywheel nut? Looks to be 1" but I would like to know for sure before I buy a socket that will fit the nut, as I will never use a socket that big for anything else probably. I have them up to 3/4" only. Thanks all.

No points on the motor. You will need a flywheel removal tool as well plus an alignment ring.

Might need to find a buddy to help you figure out that fine motor.

Oh boy. I have access to a wheel puller, but do not know what an alignment ring is or what it's for. Maybe i better take it to a mechanic.

Will I need to have to re-align anything if I just remove the flywheel and just look at the coils to see if they are destroyed before replacing the flywheel if everything looks o.k.? I replaced the power pack today but will not be going to the lake until Tues or Wed. I could start it in my driveway on muffs, but it would be much better with a load on it, I think, for seeing if it still shuts off while running. Hoping I was losing the spark because that old power pack was getting hot is all it was. My fingers are crossed.

STOP-----You can test all the components under the flywheel.----No need to remove the flywheel !-----Stuff under the flywheel is very reliable in my opinion.----Don't waste beer tokens, do some testing !

That sounds good. I will go on line and research how to test things. I did see how to test the stator without taking the flywheel off, but could not find anything on testing the coils yet, but I will search it out. I can probably find the specs on line if I find the way to test them. Thanks.
EDIT: Do you think I did any good by replacing the power pack for my shutting off problem? The motor just shut off like someone shut the key off, and would not start again for a few minutes. After I limped back to the dock, I ran the motor at idle for a good 10 minutes with no problem (also, no load, correct)? The only thing that was kind of hot was the top of the flywheel at that time.

By the way (saltchuckmatt) I did look up what the alignment ring is for. It is about $80 and up.

 

[racerone]

That ring is a factory / shop time saver !-----Not needed if you take the time to adjust parts.-----I doubt you need to replace anything under the flywheel.-----Unless a screw was loose in there and wiped everything out.

Well, again, I have my fingers crossed that the only problem I may have had when the motor was shutting off was just the power pack. I bought a new one for under $50 (Sierra brand) so I figured I would start there and it was very easy to replace the old one. If I still have the same problem, i don't know what to do next. The motor shut off just like someone shut the key off, and would not start back up (would crank real good but no spark)? After about 10 minutes, it started back up, ran at idle or just above idle real good , but when I went cruising speed or WOT, it would run a few minutes then shut off again. No hesitation, no bogging down, no coughing, missing or anything, but shut off like someone shut the key off again and again. Ran fine at the dock when I made it back to the dock at idle speed for a long time.

you can simulate heat stroke with a hair dryer if you have 120v at the dock.
use an IR gun to see what temp it cuts out , and check cooling .
it does sound like the PP is failing.

I do not think the PP will fail now for sure as I renewed it. LOL I have a heat gun I can use to simulate the motor heating up, but I would not know where to point the thing. At the flywheel to heat things up under it?? T.Y.

you probably fixed it already.

Thanks for the encouragement and I really hope I did too!!!
