97 Sea Doo Speedster Tachometer

[Wiso73]

Hey,

My name is Luis and I have a 97 Sea Doo Speedster with two 717 rotax engine. I
was wondering if anyone can help me out by telling me where the RPM cable is
located. One of my tachometer is not working. But I know the actual tachometer
work because I switch it to the other engine and it works fine. Does anyone know
what can be the problem.

Thanks,
Luis
