I am not an expert on vehicle electronics but the way I understand it is that if you use a tach made for multi cylinder engines on a single it will read double the RPM hence your reading of 6000 RPM when you are looking for 3000 RPM.
As a side note the PDF link you posted is to car electrical diagrams and not a SeaDoo.

Oh my bad I thought that was for cars. Like I said before I know nothing about Ski doos or other powered watercraft. Hope you get it figured out

My guess is that the Skidoo was a twin cylinder and computed Rev on the firing stroke, since you have a single cylinder every stroke is a firing stroke...
