I just bought this motor and boat combo (2001 Yamaha C90). I also have the Yamaha OEM Service Manual. The motor is very, very hard to start from a cold state (not run for awhile). I've tried to learn through web searches and sites like this and it seems the culprit is the Fuel Enrichment Valve. The single "BLUE" wire from the valve goes nowhere, it's Ty-Rap'd and capped at the harness. The wire diagram in the manual is extremely hard to read as all the text is so tiny and fuzzy. Can this valve just be powered by 12V using a momentary switch for start up or does it "HAVE" to be wired to something on the motor. Motor restarts once run awhile instantly.
