[interrider1]

Can anyone please tell me, what computer is compatible for seadoo 1994 657. The ski computers last Three digits are 071, it has white wire.
And does the new computer (if there's one) do you still need ignition module.

I don't know much at all about the pre 1996 skis but I have gray boxes complete. I have a couple of MPEMs I use for testing that are 1996 SPI and those are compatible with other skis. Not sure if the MPEM timing is different on the 657X. What fried my MPEM on my 1996 SPI was the rectifer. One moment I was wide open, next moment dead in the water.... nothing. You can send my a part number and I can check.
