First Review: Great price, next day delivery. Unfortunately the unit was dead on arrival. I used the SeaDoo repair guide to fix the problem and found this MPEM not working. I'm waiting for a replacement device and hope the next one will work. Second review: After receiving the DOA MPEM module, I sent the DOA device back and received a replacement 5 days later. I successfully installed the device and it works. Took a SeaDoo GTS to Lake Michigan to drive 6ft. rolling shafts. The block worked perfectly. The only thing that confuses me is that there are no specs, diagrams or instructions of any kind.
