1993 Searayder sportjet 90- FLYWHEEL

[Teeko]

I bought the flywheel from "PartsVu" out of Florida as shown in photo above ($550). When removing the flywheel take note of what color Stator (Red or Black) you have underneath as this will dictate parts. Read the whole thread & any links & you will get the jist of what took place. Most threads are problem specific or will help give an understanding of problem. I am NOT a mechanic & did not do the work. But I am mechanically inclined & understood the threads & discussions for the most part. This greatly assisted me in obtaining the correct parts. My mechanic was doing this as a side job & tasked me to obtain parts. After flywheel was installed, I still had to spark, so mechanic had me purchase an "electronic switch box" ($250-CDI brand from PartsVu). After installing that , he water tested it & said it was running terrific! I was going to test last week myself but need to re-wire all trailer lights first. UGH! Good Luck.

Thanks. Any pointers on removing the flywheel? I used a puller and it already pulled one of the 3 bolts from the flywheel. Either I have to retap the holes oversize or try a 3 jaw puller.

Heat, penetrating oil and the biggest impact gun you have.

Flywheel came off easily with a 3 jaw puller. 4 of 6 magnets are loose but I believe I caught it just as it happened. There looks to be no damage to the stator. I have the "black" stator. Any ideas if your flywheel you got would work on a black stator? Just trying to make sure before I pull the trigger

so I had the same issue with magnets coming loose. I went to a local boat mechanic and he had a force flywheel with the same casting number except it was for a 2 cyl. I heated the outside of the casting up with a standard propane torch and was able to easily break the adhesive free. After harvesting the magnets from the donor flywheel, i used 2 part epoxy to glue them onto the original.
The boat has other issues preventing it from working correctly but the flywheel repair DID work and the motor ran today. I spend 100 bucks on the used flywheel, just to get the magnets off of it. That's 100 CAD. I sourced out 650USD for new, 375USD used or 960CAD new. Not bad.

Is it possible to mix up the polarity of the magnets?
I had same problem. I glued the loose magnets back on, but now it won't run, it just pops a little. Like a weak spark.

Does anyone know the measurements of the spacing between the magnets on a 94 force mercury sports jet boat
