2007 Speedster ECM cross over

[LRG5]

I have a 2007 seadoo speedster 150 NA it only has 28 hours on the motor, and the ECU went bad and was holding the number 3 injector open filling the cylinder with gas. I have check all the wiring and know the short is in the ECU and No blown fuses. A new ECU is over $800.00, and was looking into used. Is there a cross over list of ECU that will work in my speedster. The OEM part number for the ECU is 420664136. Thinking a jet ski or new or old ECU would work in the speedster.
