MPEM that works for 1999-2000 GTX

[bm1961]

I have a 1999 Seadoo GTX that recently had to have a new key coded. i noticed that the mpem in the 1999 gtx jet ski was number 278001526. This jet ski was supposed to have the 278001398 or 278001525 mpem.

It’s been working fine with no problems
Recently I acquired a 2000 GTX. The mpem installed in this jet ski was the 278001525. This mpem was working fine but just recently went dead. I wanted to know if the 278001526 mpem would be an alternate replacement for the 278001525, since it apparently works in the 1999 GTX?

Should work fine as both those skis should have the dual coil ignition. Put the working one in the other ski and see if it runs.

The transition year for a Seadoo 951 was 1998 to 1999. Difference is in the stator and the number of poles on the stator flywheel. These motors (1998) needed a different ignition setup and MPEM. All other years that I know of in a 951 should have interchangeable MPEMs at least as far as the motor circuit.

The best way to see is to check the circuit diagrams in the shop manual and make sure they are interchangeable.
