Need Help Please

[DarkBlue]

Hey all,

I have a 2000 Yamaha 100 hp four stroke on my boat, not fuel injected. Today when I went out to start it it would not turn over when I turned the key. Played with the wiring a bit on the ignition and it turned over and fired up, but the dash guages were not working. Tried to accelerate the motor and it would accelerate some, and ran like crap. After about 5-10 minutes of idling the gauges started working and the motor ran just fine. Cruised around for a bit and shut it down, and when I tried to start it the same thing happened, and is still happening. What in the world is going on? Any help would be great before I bite the bullet and take it to the shop.

Thanks much,

Chris

I would start with ground at battery. It did start so engine wires must be ok? Guages not working steady usually is from a bad or weak ground wire. good luck !I had engine problems recently and my 4 yr old grand daughter found a hanging wire under dash!!! sometimes its just something so simple its overlooked.
