WTB 240 sportjet powerhead or equivalent?

[ME_man]

I recently acquired a 2003 Seadoo speedster in a trade. The engine came disassembled in 3 totes. After brief research I’ve learned the engine is a 210 hp carb model(with a large chunk missing from the block) not the original 240hp efi engine. I’m looking for a complete replacement 240 efi - needing rebuild is ok if the price is right- or a efi powerhead which will work with the m2 jet drive. I’ve seen there’s a 250 optimax jet drive which I’m interested in.. it appears I would need a different adapter plate.. also I’ve read some speculation of possibly using an outboard powerhead?.. if a 250 or 225 optimax would work.. I might be interested in buying one of you have it.. thanks
