95 Flywheel VS 97 Flywheel on Sport Jet 120

I swapped my Sport Jet powerhead from a 95 - 97 The flywheel from 95 would not fit the 97 the hole is smaller on 95 so I am using the 97 flywheel. The only other thing different is the inner magnet for the trigger. On the 97 there are 2 groves 180 degrees from one another, the 95 has a solid magnet. The 97 had a CDM ignition the 95 had a CDI Switchbox ignition. Will the groves in the 97 flywheel have an effect on the 95 ignition components, mainly the trigger? I ask this because with this setup I am only getting spark when the trigger is advanced and only spark intermittently with the trigger in the neutral position. Thanks in advance for any help.

Re: 95 Flywheel VS 97 Flywheel on Sport Jet 120

UPDATE: Turns out the answer is no.

I had a 95 that went south on me, took it to a place to be rebuilt, they were taking forever (2 months) to get the job done. In the meantime while they were rebuilding the 95 I came across a used 97 with low hours that I purchased in the hopes of putting it in the boat and be on my way. Of course that didn?t work. The 95 finally got finished so I put it in and used the same 95 electronics I had on the 97 that wasn?t giving me spark and she fired up just fine.

My conclusion as to why the 97 would not fire with the 95 electronics is the flywheel from the 95 does not fit on the 97 powerhead because the crankshaft diameter. The stator and trigger from a 95 bolted up on the 97, however I needed to use the 97 flywheel. The 97 flywheel has 2 groves in the inner magnet where the 95 is a solid magnet. This caused the 95 trigger not to fire correctly.

So I have a nice clean 97 Sport Jet 120 powerhead looks to be recently rebuilt all cylinders are at 150psi up for sale if anyone is interested.
