You probably read my flywheel adventure where I had too many broken magnets and I had to break down and buy a new flywheel.  I just used a fridge magnet to determine alternating polarity.  Any magnet will work and it was easier to handle a smaller weaker magnet.

The magnets don't have squat to do with timing btw.  The crankshaft position sensor is the input for the timing.  Glad you got it working.

I am for supporting local dealers to a point, but if the part is 800 at the dealer and 600 online and we both have to order it and when I order it, it comes to my house instead of me having to leave work to go to a 9-5 dealership, and they tell you something can't be done when in fact in can, where is the value add there?

Update, 2017. 

2.5 seasons on the repaired Flywheel and it is still running perfect.

I'm currently facing the same flywheel issues and here are my findings :

when flywheel magnets fall off, the engine will still run but poorly at idle due to fluctuation below 55v in 55v circuit but what i found out was whenever the battery is fully charged by the outboard and voltage reaches 14.3 to 14.5v you will start to notice the 55v circuit voltage rise slowly until it reaches 55v then the outboard will run smoothly and whenever there's any battery drain at idle by trimming the motor for example you'll notice battery voltage drop below 14.3 then 55v circuit voltage will also drop and start to fluctuate until battery voltage is back to 14.3 to 14.5v which means etecs give priority to the 12v charging circuit over the 55v circuit.

if throttle is increased above idle while the 55v circuit is fluctuating below 55v the alarm will sound and motor will enter safe mode.

my boat has twin engines, so to avoid safe mode i start both of my engines and raise the throttle on my good one until battery voltage reaches 14.5 which will make my other engine reach 55v and smooth out at idle then i can shift forward with no alarms.

Dude thanks for your explanation about the flywheel.
I have the same situation but I have 5 broken magnets!! How can I put the magnets ?
I supposed in the opposite way as you did, but you only had 2 broken magnets, I have 5 and two of them are broken in many pieces.

Would be any way to solve it? Please if you know how to do it, would be great, I’m in a small town where is almost impossible to te a new flywheel.

Thank you

Hi. Yes. I just had to fix my other engine this spring. So now both my engines have been repaired with the methods I described. I had two broken ones in this engine also. I made sure I glued the biggest pieces in on opposite sides of the flywheel so that it would produce the least amount of current fluctuation.
So if you don’t have anything left to work with, I did find a kit. Someone made a kit with 4 magnets. It comes with directions (I’m suspicious if they are the directions I wrote a couple years ago) and glue for $100. It’s on EBay and Amazon. It’s probably the only way to get some new magnets. Other option would be to visit a local Evinrude shop and see if they have any old ones they are throwing out. Maybe make a deal. Or last option is to buy a used one and steal parts from it.

Good luck. Be sure to place the magnets in an alternating pattern based on polarity. When you glue them in if you don’t have a magnet on either side the lose one will want to migrate to the other before the glue dries. Be carful to catch that before the glue sets.

Thanks for the answer!

Few questions,
- I put the broken magnets (biggest piece) in front of the other broken piece. So I can leave 1-2-1-2 etc

BUT, how should I do, with the 5th magnet, I have two pairs broken but one is alone, I supposed that the opposite of that one must be a full piece magnet right? Or will be better to use a broken piece?

- the broken piece of magnet, did you put it right in the center where the real magnet must be? Or cornered?

- is this a usual problem in evinrude flywheels ?

I saw the item on eBay and Amazon, we were thinking about getting two packs (8 magnets) to replace this ones, but I’m far away from USA and takes a few weeks to arrive, so for now we must find a quick solution.

Thanks you again !

I would not want two broken pieces close to each other. Use the biggest piece or even a couple of the biggest pieces and glue them in center to the gap between magnets.

If you have two spots next to each other that have broken pieces I would carefully remove a good one from opposite side and replace broken one there. Try to think this way...the fly wheel needs to be balanced like a car tire. So broken pieces on opposite sides of each other will help maintain balance. Next is electricity is being generated. Each broken piece will create a small dip in voltage. So best not to have two next to each other.

Now I also found magnets that looked ok but were ready to come off. I suggest you use a screw driver and tap every magnet looking for a lose one that first looked ok.
