Been looking at the Hydrotec phase II kits,anyone tried these yet? Read B&W magazine's write up on the 250 hpdi/phase II,and thought it looked encouraging.

Thinking about doing the work myself,but it will be a first for me. Looks fairly simple,only thing that really skeers me is all the wiring and plumbing.:rolleyes:

First get a factory service manual for that motor and study the sections to do with what you are planning on changing. Yamaha wiring is pretty simple. Color to color and plug ups won't interchange. The little pieces of tape with numbers work good to keep up with which hose goes where.

Thanks Ray, I pulled the cowling lastnight to study it a little,doesn't look too bad. I'll order a manual,and plan on taking some digitals for later reference also.


Is there anyone out there re-mapping fuel curves yet?
